| 1 | Smart Substation Integration Technology and Its Application in Distribution Power Grid显示文摘At present,smart substations use the IEC61850 standard based on the architectural framework of three layers and two networks to realize information digitization and advanced applications.Although the smart substation offers many improvements in design,equipment manufacturing,and construction,the intelligent devices used in smart substations are costly,and are also difficult to maintain since they are dispersed within a single unit.Functionality optimization and device integration,thus,have become important issues in smart substation development.This paper presents an integrated solution and implementation process for a smart substation system.In the process layer,an integrated intelligence component is developed that functions both as an intelligent terminal and a merging unit.In the bay layer,an integrated station-area protection measurement and control master device is designed to achieve such functions as protection,monitoring,control,fault recorder,and power quality monitoring.Finally,in the station control layer,an integrated information platform is established to bring together various system functions and to promote interactive sharing.Integration technology improves the economy and practicality of the smart substation,especially in a distribution power grid. | Qipeng Song Wanxing Sheng Lingfeng Kou Dongbo Zhao Ziping Wu Hengfu Fang Xiaolong Zhao | 2016 | CSEE Journal of Power and Energy Systems2016，2，4： | 6 |
| 2 | The electromechanical features of LiNbO_(3) crystal for potential high temperature piezoelectric applications显示文摘Lithium niobate(LiNbO_(3),LN)crystal is a multi-functional material with favorable piezoelectric,nonlinear optical and electro-optic properties.In this study,the electromechanical properties of the radial extensional(RE)and the thickness extensional(TE)modes of the congruent LN are studied and the temperature dependent behaviors are revealed.The RE mode electromechanical coupling factors(kp)for the Y-and Z-oriented discs are calculated and found to be 3.8%and 24.7%,respectively,which are nearly the same as the experimental results of 3.8%and 25.2%,respectively.The maximum RE and thickness shear(TS)modes electromechanical coupling factors are obtained to be 47.6%and 68.5%for the Yx/25and Yx/167crystal cuts,respectively.The LN crystal possesses good temperature stability of the electromechanical coupling factors(RE and TE modes)from 20℃ to 500℃,where the variations of kp and kt for the Y-oriented discs are<8.0%and<1.8%,respectively. | Feifei Chen Lingfeng Kong Wei Song Chao Jiang Shiwei Tian Fapeng Yu Lifeng Qin Xian Zhao | 2019 | Journal of Materiomics2019，5，1： | 3 |
| 3 | Berlin Green Framework‑Based Gas Sensor for Room‑Temperature and High‑Selectivity Detection of Ammonia显示文摘Ammonia detection possesses great potential in atmosphere environmental protection,agriculture,industry,and rapid medical diagnosis.However,it still remains a great challenge to balance the sensitivity,selectivity,working temperature,and response/recovery speed.In this work,Berlin green(BG)framework is demonstrated as a highly promising sensing material for ammonia detection by both density functional theory simulation and experimental gas sensing investigation.Vacancy in BG framework offers abundant active sites for ammonia absorption,and the absorbed ammonia transfers sufficient electron to BG,arousing remarkable enhancement of resistance.Pristine BG framework shows remarkable response to ammonia at 50–110°C with the highest response at 80°C,which is jointly influenced by ammonia’s absorption onto BG surface and insertion into BG lattice.The sensing performance of BG can hardly be achieved at room temperature due to its high resistance.Introduction of conductive Ti3CN MXene overcomes the high resistance of pure BG framework,and the simply prepared BG/Ti3CN mixture shows high selectivity to ammonia at room temperature with satisfying response/recovery speed. | Tingqiang Yang Lingfeng Gao Wenxuan Wang Jianlong Kang Guanghui Zhao Delong Li Wen Chen Han Zhang | 2021 | Nano-Micro Letters2021，13，4： | 2 |
| 4 | Wheat MADS-box gene TaSEP3-D1 negatively regulates heading date显示文摘The MADS-box gene plays an important role in regulating plant growth and development.In this study,a SEP3-like MADS-box gene TaSEP3-1 was isolated from bread wheat.The expression patterns of the three homoeologs TaSEP3-A1,TaSEP3-B1,and TaSEP3-D1 were similar,and higher expression levels were detected in floral organs and developing kernels.TaSEP3-D1 was located in the nucleus and cytoplasm and possessed transactivation activity in yeast.Homoeolog sequence polymorphism analysis identified four,three,and four haplotypes of TaSEP3-A1,TaSEP3-B1,and TaSEP3-D1,respectively,and the haplotypes of TaSEP3-D1 had larger effects on agronomic traits than those of TaSEP3-A1 and TaSEP3-B1.D1_h4,significantly associated with heading date,plant height,and other yield-related traits,was the favored haplotype of TaSEP3-D1.Transgenic wheat genotypes overexpressing TaSEP3-D1 exhibited delayed heading and reduced plant height,indicating a role in regulating heading date and plant development.These results shed light on the role of TaSEP3-D1 in wheat plant development.The favored haplotype of TaSEP3-D1 can be applied in breeding to improve plant architecture and yield in wheat. | Lei Zhang Hao Zhang Linyi Qiao Lingfeng Miao Dong Yan Pan Liu Guangyao Zhao Jizeng Jia Lifeng Gao | 2021 | The Crop Journal2021，9，5： | 2 |
| 5 | Mycorrhizas Affect Polyphyllin Accumulation of Paris polyphylla var.yunnanensis through Promoting PpSE Expression显示文摘Paris polyphylla var.yunnanensis is a traditional Chinese medicinal plant,in which polyphyllin as the main medicinal component is an important secondary metabolite with bioactivity.Arbuscular mycorrhizal fungi(AMF)have multiple positive effects on plants,while it is not clear whether AMF increase the content of medicinal components in medicinal plants.In this study,a total of nine AMF treatments were laid to analyze the mycorrhizal effect on polyphyllin accumulation and PpHMGR and PpSE expression of P.polyphylla var.yunnanensis.AMF increased the content of polyphyllin in the cultivated variety with low relation to the increase of inoculation intensity.Polyphyllin I,II,and VII were identified and partly improved by AMF inoculation,dependent on AMF treatments and culture environments.Similarly,the PpHMGR and PpSE expression was induced by mycorrhization,dependent on AMF species,whilst the induction was more obvious in PpSE than in PpHMGR after mycorrhization.It concluded that the symbiotic relationship between P.polyphylla var.yunnanensis and AMF increased polyphyllin content level in the plant,which was associated with the up-regulation of PpSE transcripts. | Hailing Li Lingfeng Xu Zhuowei Li Shunxin Zhao Dongqin Guo Lu Rui Nong Zhou | 2021 | Phyton-International Journal of Experimental Botany2021，90，5： | 2 |
| 6 | Grazing by microzooplankton and copepods on the microbial food web in spring in the southern Yellow Sea,China显示文摘Assessment of microzooplankton and copepods grazing pressure on picoplankton is a key requirement for resolving the microbial food web efficiency.Although microzooplankton grazing on picoplankton has been extensively studied,the impact of microzooplankton on different groups of picoplankton,i.e.,heterotrophic bacteria,Synechococcus and picoeukaryotes have rarely been compared.Furthermore,in the very few existing studies there is no consistent evidence of an enhancing or restraining effect of copepods on picoplankton.More studies are needed to improve our understanding of the influence of microzooplankton and copepod on picoplankton.Dilution incubations and copepod addition incubations were performed during a cruise to the southern Yellow Sea on May 16-29,2007.The bulk grazing of microzooplankton and the calanoid copepod Cal anus sinicus on phytoplankton,flagellates and picoplankton was estimated.Stations were divided into either eutrophic or oligotrophic according to the nutrient and biological parameters.Picoplankton comprised a large part of the diet of microzooplankton in the central oligotrophic area,while phytoplankton was the main food of microzooplankton in the coastal eutrophic area.In the central oligotrophic area,microzooplankton preferred grazing on Synechococcus.After copepod addition,ciliate abundance decreased while Synechococcus abundance increased(382%,64%and 64%at three experimental stations,respectively),indicating strong grazing pressure of microzooplankton on Synechococcus.Our results suggest that Synechococcus might be an essential carbon source the planktonic food web in the oligotrophic waters of southern Yellow Sea. | Yuan Zhao Yi Dong Haibo Li Shiquan Lin Lingfeng Huang Tian Xiao Gerald Gregori Li Zhao Wuchang Zhang | 2020 | Marine Life Science & Technology2020，2，4： | 1 |
| 7 | Yield Effect of Chemical and Soil Nitrogen on the Mid-season and Ratooning Hybrid Rice显示文摘Using hybrid rice Yixiang1577 as the material,the mid-season and ratooning hybrid rice yield variation was studied in Southern Sichuan at different levels of nitrogen fertilizer. The results showed that rice yield by using N fertilizer increased to the most signifi cant level than no fertilizer ones,and the mid-season rice and rice yield by using more N fertilizer increased to the signif icant level than less fertilizer ones. The rice yield by using no fertilizer ones increased to the most signif icant level than some used fertilizer,and the ratooning rice and rice yield by using more N fertilizer decreased to the most signifi cant level than less fertilizer ones. The rice yield by using some fertilizer increased to the most signif icant level than no fertilizer ones for mid-season+rationing rice and rice yield by using some fertilizer had no obvious differences at different nitrogen levels. Therefore,application of fertilizer can improve yield of mid-season rice and mid-season+rationing rice. Soil test results showed that nutrient contents in rice fi eld in South Sichuan were very rich in nitrogen,which could provide more adequate crop growth potential soil nitrogen nutrition. The crops with a deep root system had stronger ability of utilization on soil nitrogen. Therefore,the ratooning rice used no or little N fertilizer had a high yield performance because they made full use of soil nitrogen with deep root system. | BAO Lingfeng LINT Gang ZHAO Deming LI Yunwu HE Bin | 2009 | Journal of Northeast Agricultural University(English Edition)2009，16，3： | 1 |
| 8 | Prediction of combined cycle fatigue life of TC11 alloy based on modified nonlinear cumulative damage model显示文摘The nonlinear cumulative damage model is modified to have high prediction accuracy when the high-low cycle stress frequency ratio m is large(m500).The low cycle fatigue(LCF)tests,high cycle fatigue(HCF)tests and combined high and low cycle fatigue(CCF)tests of TC11 titanium alloy were carried out,and the influencing factors of CCF life were analysed.The CCF life declines with the decrease of the ratio of high-low cycle stress frequency m.Both linear and nonlinear cumulative damage models are used to predict the CCF life.The CCF life prediction error of the linear cumulative damage model is great and the predictions tend to be overestimated,which is dangerous for engineering application.The accuracy is relatively high when the high-low cycle stress frequency ratio m500.The accuracy of nonlinear cumulative damage model is higher than that of linear model when the high-low cycle stress frequency ratio m500.Based on the relationship between high cycle average stress rmajor and material yield limit rp,0.2,a correction term is added to the nonlinear cumulative damage model and verified,which made the modified model more accurate when m500. | Zhenhua ZHAO Kainan LU Lingfeng WANG Lulu LIU Wei CHEN | 2021 | Chinese Journal of Aeronautics2021，34，7： | 1 |
| 9 | Targeted mutagenesis in Arabidopsis thaliana using CRISPR-Casi2b/C2ci^°°显示文摘Casi2b/C2ci is a newly identified class 2 CRISPR endonuclease that was recently engineered for targeted genome editing in mammals and rice.To explore the potential applications of the CRISPR-Casi2b system in the dicot Arabidopsis thaliana,we selected BvCasi2b and BhCasi2b v4 for analysis.We successfully used both endonucleases to induce mutations,perform multiplex genome editing,and create large deletions at multiple loci.No significant mutations were detected at potential off-target sites.Analysis of the insertion/deletion frequencies and patterns of mutants generated via targeted gene mutagenesis highlighted the potential utility of CRISPRCasi2b systems for genome editing in Arabidopsis. | Fan Wu Xinyu Qiao Yafei Zhao Ziyi Zhang Yifan Gao Lingfeng Shi Haokun Du Lulu Wang Ya-Jie Zhang Yu Zhang Langyu Liu Quan Wang Dejing Kong | 2020 | Journal of Integrative Plant Biology2020，62，11： | 1 |
| 10 | Mycorrhizal Fungal Effects on Growth,Antioxidant Capacity,and Medicine Quality of Paris polyphylla var.yunnanensis显示文摘A field experiment was conducted to determine the effects of two commercial strains composed of mulple arbuscular mycorrhizal fungi(AMF)species on plant growth,antioxidant capacity,and medicine quality of Paris polyphylla var.yunnanensis in three subtropical soils from Wanzhou,Anshun and Baoshan in fields.The results showed that AMF inoculation enhanced the fungal colonization rate and activities of both succinate dehydrogenase and alkaline phosphatase,thereby,enhancing the mycorrhizal viability of P.polyphylla var.yunnanensis.The concentrations of photosynthetic pigments(chlorophyll a,b,a+b and carotenoids),soluble sugar,soluble protein and photosynthetic capacity were higher in AMF-inoculated plants than in non-AMF-treated plants in field.AMFtreated plants recorded higher activities of catalase,peroxidase and superoxide dismutase,and caused the reduction in malondialdehyde content,indicating lower oxidative damage,compared with non-AMF plants.Polyphyllin I,Polyphyllin II,Polyphyllin III,Polyphyllin IV and total polyphyllin contents were increased by AMF treatment.In conclusion,AMF improved the plant growth,antioxidant capacity and medicinal quality of P.polyphylla var.yunnanensis seedlings.Hereinto,AMF effects on the soil from Wanzhou was relatively greater than on other soils. | Nong Zhou Lingfeng Xu Min Yang Dongqin Guo Qiuxia Gan Jingjing Zhao | 2021 | Phyton-International Journal of Experimental Botany2021，90，3： | 1 |

| 13 | Improved methodology for efficient establishment of the myocardial ischemia-reperfusion model in pigs through the median thoracic incision显示文摘To investigate the feasibility and effectiveness of establishing porcine ischemia-reperfusion models by ligating the left anterior descending(LAD)coronary artery,we first randomly divided 16 male Bama pigs into a sham group and a model group.After anesthesia,we separated the arteries and veins.Subsequently,we rapidly located the LAD coronary artery at the beginning of its first diagonal branch through a mid-chest incision.Then,we loosened and released the ligation line after five minutes of pre-occlusion.Finally,we ligated the LAD coronary artery in situ two minutes later and loosened the ligature 60 min after ischemia.Compared with the sham group,electrocardiogram showed multiple continuous lead ST-segment elevations,and ultrasound cardiogram showed significantly lower ejection fraction and left ventricular fractional shortening at one hour and seven days post-operation in the model group.Twenty-four hours after the operation,cardiac troponin T and creatine kinase-MB isoenzyme levels significantly increased in the model group,compared with the sham group.Hematoxylin and eosin staining showed the presence of many inflammatory cells infiltrating the interstitium of the myocardium in the model group but not in the sham group.Masson staining revealed a significant increase in infarct size in the ischemia/reperfusion group.All eight pigs in the model group recovered with normal sinus heart rates,and the survival rate was 100%.In conclusion,the method can provide an accurate and stable large animal model for preclinical research on ischemia/reperfusion with a high success rate and homogeneity of the myocardial infarction area. | Liuhua Zhou Jiateng Sun Tongtong Yang Sibo Wang Tiankai Shan Lingfeng Gu Jiawen Chen Tianwen Wei Di Zhao Chong Du Yulin Bao Hao Wang Xiaohu Lu Haoliang Sun Meng Lv Di Yang Liansheng Wang | 2023 | The Journal of Biomedical Research2023，37，4： | 1 |
| 14 | Analysis and Design Innovation on Underground Gasifier for Medium-Deep Coal Seam显示文摘Over the past 80 years,dozens of underground coal gasification(UCG)mine field tests have been carried out around the world.However,in the early days,only a small number of shallow UCG projects in the former Soviet Union achieved commercialised production.In this century,a few pilot projects in Australia also achieved short-term small-scale commercialised production using modern UCG technology.However,the commercialisation of UCG,especially medium-deep UCG projects with good development prospects but difficult underground engineering conditions,has not progressed smoothly around the world.Considering investment economy,a single gasifier must realise a high daily output and accumulated output,as well as hold a long gasification tunnel to control a large number of coal resources.However,a long gasification tunnel can easily be affected by blockages and failure,for which the remedial solutions are difficult and expensive,which greatly restricts the investment economy.The design of the underground gasifier determines the success or failure of UCG projects,and it also requires the related petroleum engineering technology.Combining the advantages of the linear horizontal well(L-CRIP)and parallel horizontal well(P-CRIP),this paper proposes a new design scheme for an“inclined ladder”underground gasifier.That is to say,the combination of the main shaft of paired P-CRIP and multiple branch horizontal well gasification tunnels is adopted to realise the control of a large number of coal resources in a single gasifier.The completion of the main shaft by well cementation is beneficial for maintaining the integrity of the main shaft and the stability of the main structure.The branch horizontal well is used as the gasification tunnel,but the length and number of retracting injection points are limited,effectively reducing the probability of blockage or failure.The branch horizontal well spacing can be adjusted flexibly to avoid minor faults and large cracks,which is conducive to increasing the resource utilisation rate.In addition,for multi-layer thin coal seams or ultra-thick coal seams,a multi-layer gasifier sharing vertical well sections can be deployed,thereby saving investment on the vertical well sections.Through preliminary analysis,this gasifier design scheme can be realised in engineering,making it suitable for largescale deployment where it can increase the resource utilisation rate and ensure stable and controllable operations.The new gasifier has outstanding advantages in investment economy,and good prospects for application in the commercial UCG projects of medium-deep coal seams. | Kong Lingfeng Zhan Enqiang Zhao Chenhui | 2019 | China Oil & Gas2019，26，4： | 1 |
| 15 | Analysis and Design Innovation on Underground Gasifier for Medium-Deep Coal Seam(Ⅱ)显示文摘Poor investment economy under current technical level In terms of economy and due to the factors including environmental protection,coal quality,coal seam thickness,geological conditions and mining scope,the potential of UCG business in China is mainly in mediumdeep coal seams.Due to its low calorific value and low value,brown coal has basically no open-pit mining or underground mining value,and can only be exploited and utilised by UCG once its burial depth exceeds 500 m.Most of the bituminous coal with a burial depth of less than 1,000 m also exceeds the economic lower limit of underground mining,and“underground coal gasification”becomes an important option. | Kong Lingfeng Zhan Enqiang Zhao Chenhui | 2019 | China Oil & Gas2019，26，6： | 0 |
| 16 | Performance analysis of a photovoltaic/thermal system with lunar regolith-based thermal storage for the lunar base显示文摘Powering a moon base,especially keeping it warm during the long lunar night,is a big challenge.This paper introduces a photovoltaic/thermal(PV/T)system incorporating regolith thermal storage to solve the challenge of power and heat provision for the lunar base simultaneously.The vacuum of space around the moon helps this system by reducing heat loss.During the moon's daytime,the system not only generates electricity but also captures heat.This stored heat in the regolith is then used at night,reducing the amount of equipment we need to send from Earth.The spectrally selective PV/T panels are designed to absorb a wide range of sunlight(0.3–2.5μm)while minimizing heat loss in the infrared range(3–30μm).Simulation results of the hybrid solar energy system indicate the average value of the overall efficiency is 45.9%,which relatively elevates 56.1%compared to the PV system.The launch mass of the proposed PV/T system is only 8.4%of a traditional photovoltaic-lithium battery system with the same amount of energy storage.And the total specific energy of the proposed system is 7.3 kWh kg^(-1),while that of the photovoltaic-lithium battery system is about 0.3 kWh kg^(-1).In summary,this study proposes an alternative combined heat and electricity supply system for the lunar base,which can greatly reduce the launch mass and free up load for other scientific research equipment. | SUN WenGan ZHAO Bin PEI Yu SHI LingFeng HU MaoBin LI MuJun REN Xiao PEI Gang | 2024 | Science China(Technological Sciences)2024，67，4： | 0 |
| 17 | (Ca,K)(Zn,Mn)_(2)As_(2):Ferromagnetic semiconductor induced by decoupled charge and spin doping in CaZn_(2)As_(2)显示文摘We have successfully synthesized a novel diluted magnetic semiconductor(Ca_(1−2x)K_(2x))(Zn_(1−x)Mn_(x))_(2)As_(2) with decoupled charge and spin doping.The substitutions of(Ca^(2+),K^(+))and(Zn^(2+),Mn^(2+))in the parent compound CaZn_(2)As_(2)(space group P m1(No.164))introduce carriers and magnetic moments,respectively.Doping only Mn into CaZn_(2)As_(2) does not induce any type of long range magnetic ordering.The ferromagnetic ordering arise can only when K^(+)and Mn^(2+)are simultaneously doped.The res-ulted maximum Curie temperature reaches~7 K,and the corresponding coercive field is~60 Oe.The transport measurements confirm that samples with K and Mn co-doping still behave like a semiconductor. | Jinou Dong Xueqin Zhao Licheng Fu Yilun Gu Rufei Zhang Qiaolin Yang Lingfeng Xie Fanlong Ning | 2022 | Journal of Semiconductors2022，43，7： | 0 |
| 18 | Investigation on Agronomic Characters of Dwarf Mutant 778 in Broomcorn Millet(Panicum miliaceum L.)and Analysis of Its Sensitivity to GA显示文摘In order to investigate the differences between agronomic traits of dwarf mutant and original material 260 and whether the cause of dwarf is related to GA synthesis or signaling pathway,this experiment used dwarf mutant 778 and its original material 260 as experimental materials.Morphological observation and determination were performed for agronomic traits on plant height,ear length,internode length,internode number,seed length,seed width and number of seeds in different growth periods and different concentrations.The plants were treated by GA spraying,and the changes of plant height,root length,stem width,leaf length and leaf width were measured.The results are as follows:①The plant height of the dwarf mutant material was significantly different from that of the original high material,which was mainly caused by the difference between above-ground basal part and the length of the first and second elongation joints.②Comparing and analyzing the differences of traits between dwarf mutant material 778 and original high material 260,it was found that the plant height,ear length,internode number,grain number per ear and internode length of dwarf mutant 778 were significantly lower than that of high stalk 260(P<0.01),and the seed length of dwarf mutant 778 was significantly higher than that of high stalk 260(P<0.05).③Different concentrations of gibberellin(0,50,100,200 mg/L)had no significant effect on plant height and root length of dwarf mutant 778(P>0.05).Different concentrations of gibberellin had significant effects on plant height,root length and sensitivity coefficient of high stalk 260(P<0.05).And compared with the control group,all high materials 260 treated with different concentrations of gibberellin performed differently in plant morphology and growth potential.④Under the conditions of 100 and 200 mg/L GA,the difference of plant height between the dwarf mutant and the high stalk control decreased with time,and there was no difference at the end.There were no differences in sensitivity coefficient GRI between different concentrations of gibberellin treatment groups,indicating that the external gibberellin could restore the scorpion dwarf mutant to the original high stalk,and the gene that causes the mutation might be related with the gibberellin synthesis pathway. | Bo ZHANG Xiaojie LIU Yingjie GUO Xiaoping JIA Dezhi YANG Yuan ZHAO Lingfeng DAI Shujun KOU Xiaomei ZHANG Dianyun HOU Xuehai ZHU | 2020 | Agricultural Biotechnology2020，9，4： | 0 |
| 19 | 3D printing critical materials for rechargeable batteries: from materials, design and optimization strategies to applications显示文摘Three-dimensional(3D)printing,an additive manufacturing technique,is widely employed for the fabrication of various electrochemical energy storage devices(EESDs),such as batteries and supercapacitors,ranging from nanoscale to macroscale.This technique offers excellent manufacturing flexibility,geometric designability,cost-effectiveness,and eco-friendliness.Recent studies have focused on the utilization of 3D-printed critical materials for EESDs,which have demonstrated remarkable electrochemical performances,including high energy densities and rate capabilities,attributed to improved ion/electron transport abilities and fast kinetics.However,there is a lack of comprehensive reviews summarizing and discussing the recent advancements in the structural design and application of 3D-printed critical materials for EESDs,particularly rechargeable batteries.In this review,we primarily concentrate on the current progress in 3D printing(3DP)critical materials for emerging batteries.We commence by outlining the key characteristics of major 3DP methods employed for fabricating EESDs,encompassing design principles,materials selection,and optimization strategies.Subsequently,we summarize the recent advancements in 3D-printed critical materials(anode,cathode,electrolyte,separator,and current collector)for secondary batteries,including conventional Li-ion(LIBs),Na-ion(SIBs),K-ion(KIBs)batteries,as well as Li/Na/K/Zn metal batteries,Zn-air batteries,and Ni–Fe batteries.Within these sections,we discuss the 3DP precursor,design principles of 3D structures,and working mechanisms of the electrodes.Finally,we address the major challenges and potential applications in the development of 3D-printed critical materials for rechargeable batteries. | Yongbiao Mu Youqi Chu Lyuming Pan Buke Wu Lingfeng Zou Jiafeng He Meisheng Han Tianshou Zhao Lin Zeng | 2023 | International Journal of Extreme Manufacturing2023，5，4： | 0 |
| 20 | (Ba_(1−x)Na_(x))F(Zn_(1−x)Mn_(x))Sb: A novel fluoride-antimonide magnetic semiconductor with decoupled charge and spin doping显示文摘We report the successful synthesis and characterization of a novel 1111-type magnetic semiconductor(Ba_(1−x)Na_(x))F(Zn_(1−x)Mn_(x))Sb(0.05≤x≤0.175)with tetragonal ZrSiCuAs-type structure,which is isostructural to the layered iron-based superconductor La(O,F)FeAs.Na substitutions for Ba and Mn substitutions for Zn introduce carriers and local magnetic moments,respectively.Ferromagnetic interaction is formed when Na and Mn are codoped,demonstrating that local magnetic moments are mediated by carriers.Iso-thermal magnetization shows that the coercive field is as large as-12000 Oe,which is also reflected in the large split between the temperature-dependent magnetization in zero-field-cooling and field-cooling condition.AC susceptibility under zero field demonstrates that samples evolve into spin-glass state below spin freezing temperature T_(f).The measurements of temperature-dependent resistivity indicate that(Ba_(1−x)Na_(x))F(Zn_(1−x)Mn_(x))Sb exhibits semiconducting behaviour. | Xueqin Zhao Jinou Dong Licheng Fu Yilun Gu Rufei Zhang Qiaolin Yang Lingfeng Xie Yinsong Tang Fanlong Ning | 2022 | Journal of Semiconductors2022，43，11： | 0 |
