摘　　要：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).
