| 2 | 锰掺杂氧化铜稀磁半导体薄膜的微结构和磁性显示文摘采用射频磁控溅射制备Mn掺杂CuO薄膜样品。X射线衍射结果说明薄膜样品为单相结构且沿(111)取向生长。通过样品的XRD精修得到样品的结构和晶格参数,掺杂后薄膜晶体结构有微小畸变。薄膜的高分辨透射电镜研究证明了对结构和晶粒大小等的精修结果,且同时说明Mn以替代Cu的形式掺入了CuO晶格中。通过对样品M-T曲线的分析,得到样品的居里温度为96.5K,近邻Mn离子之间的耦合为铁磁性,并由居里外斯拟合得到Mn离子的有效磁矩为3.1_(μB)。这说明磁性不是来自于团聚的Mn原子或铜锰的其它氧化物,而很可能来自于替住的锰离子所形成的Mn-O-Cu-O-Mn之间的铁磁性耦合。 | 赵凡 张亚萍 潘礼庆 HAO Zhu 邱红梅 赵雪丹 John Q.Xiao | 2007 | 材料导报2007，21，12： | 0 |
| 3 | Accelerated protons with energies up to 70 MeV based on the optimized SG-Ⅱ Peta-watt laser facility显示文摘The target backsheath field acceleration mechanism is one of the main mechanisms of laser-driven proton acceleration(LDPA)and strongly depends on the comprehensive performance of the ultrashort ultra-intense lasers used as the driving sources.The successful use of the SG-II Peta-watt(SG-II PW)laser facility for LDPA and its applications in radiographic diagnoses have been manifested by the good performance of the SG-II PW facility.Recently,the SG-II PW laser facility has undergone extensive maintenance and a comprehensive technical upgrade in terms of the seed source,laser contrast and terminal focus.LDPA experiments were performed using the maintained SG-II PW laser beam,and the highest cutoff energy of the proton beam was obviously increased.Accordingly,a double-film target structure was used,and the maximum cutoff energy of the proton beam was up to 70 MeV.These results demonstrate that the comprehensive performance of the SG-II PW laser facility was improved significantly. | H.H.An W.Wang J.Xiong C.Wang X.Pan X.P.Ouyang S.Jiang Z.Y.Xie P.P.Wang Y.L.Yao N.Hua Y.Wang Z.C.Jiang Q.Xiao F.C.Ding Y.T.Wan X.Liu R.R.Wang Z.H.Fang P.Q.Yang Y.E.Jiang P.Z.Zhang B.Q.Zhu J.R.Sun B.Qiao A.L.Lei J.Q.Zhu | 2023 | High Power Laser Science and Engineering2023，11，5： | 0 |
