| 1 | Evaluation of dielectric,energy storage and multiferroic properties of PrFeO_(3)-PbTiO_(3)solid solutions显示文摘This work promotes the room temperature energy storage properties of the multiferroics.In this approach,impacts of PrFeO_(3)doping on PT-based solid solutions(Pb1−xPrxTi1−xFexO_(3),x=0.21,0.22,0.23,0.24,0.25 and 0.26)have been explored.X-ray diffraction(XRD)patterns were used to estimate the crystallographic parameters,confirming the single phase tetragonal structure.The ferroelectric Curie temperature(Tc FE)is observed to drop from 410 K to below room temperature as the Pr concentration increases.The ferroelectric P-E loops were used to determine the energy storage values at room temperature.The sample x=0.24 achieved the maximum value of energy storage density of 362.25 mJ/cm^(3)with the efficiency of 40.5%.The ferroelectric P-E loops were used to determine the energy storage values at room temperature.The validity of magnetoelectric coupling in all samples was confirmed by magneto-dielectric studies and found that the sample x=0.24 shows the maximum response with the coupling coefficient(γ)=15.54 g^(2)/emu^(2). | Mehak Arora Shubhpreet Kaur Sunil Kumar Parambir Singh Malhi Mandeep Singh Anupinder Singh | 2022 | Journal of Advanced Dielectrics2022，12，5： | 0 |
| 2 | Agreement in experimental and theoretically obtained electrocaloric effect in optimized Bi^(3+)doped PbZr_(0.52)Ti_(0.48)O_(3)material显示文摘This work harmonizes the experimental and theoretical study of electrocaloric effect(ECE)in(Pb_(0.8)Bi_(0.2))(Zr_(0.52)Ti_(0.48))O_(3)solid solution by optimizing sintering temperature.Bi^(3+)-doped PbZr_(0.52)Ti_(0.48)O_(3)solid solutions were synthesized by the conventional solid-state reaction method.Different samples were prepared by varying the sintering temperature.X-ray diffraction study con-firms the crystalline nature of all the samples.An immense value of polarization has been acquired in the optimized sample.The maximum adiabatic temperature change of order 2.53 K with electrocaloric strength of 1.26 K mm kV^(−1)has been achieved exper-imentally.Whereas a comparatively close value of ECE has been acquired from the theoretical calculations using a phenomeno-logical approach.Furthermore,a large value(218 mJ cm^(−3))of thermal energy conversion has been obtained using the Olsen cycle. | Shubhpreet Kaur Mehak Arora Sunil Kumar Parambir Singh Malhi Mandeep Singh Anupinder Singh | 2022 | Journal of Advanced Dielectrics2022，12，3： | 0 |
| 3 | Enhanced magneto-dielectric response in La-doped Co_(2)U hexaferrite显示文摘The U-type hexaferrites(Ba_(1−3x)La_(2x))4Co_(2)Fe_(36)O_(60)(x=0,0.05,0.10,0.15,0.20,0.25)have been synthesized by auto-combustion method.The work involves the study of structural,microstructural,dielectric,magnetic and magneto-dielectric properties of the prepared materials.The structural analysis has been done by X-ray diffraction technique along with Le Bail refinement which confirmed the pure hexagonal phase for all the samples.The microstructural analysis has been carried out by field-emission scanning electron microscopy.The vibrating sample magnetometer is used to measure the magnetic properties.The sample with a composition of x=0.15 has shown the maximum magnetization of approximately 73.31 emu/g with the remnant magnetization of 38.89 emu/g and coercive field of 1.77 kOe at room temperature.Moreover,the same sample has delivered the maximum mag-netodielectric response of about 54.18%at 1.5-T field. | Parambir Singh Malhi Anupinder Singh Mandeep Singh Sachin Kumar Shubhpreet Kaur Mehak Arora Ashwani Kumar Sood | 2021 | Journal of Advanced Dielectrics2021，11，6： | 0 |
