Evaluation of dielectric, energy storage and multiferroic properties of PrFeO3-PbTiO3 solid solutions

Abstract

This work promotes the room temperature energy storage properties of the multiferroics. In this approach, impacts of PrFeO3 doping on PT-based solid solutions (Pb[Formula: see text][Formula: see text]Pr[Formula: see text]Ti[Formula: see text][Formula: see text]Fe[Formula: see text]O3, [Formula: see text] = 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 ([Formula: see text][Formula: see text]) 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 [Formula: see text] = 0.24 achieved the maximum value of energy storage density of 362.25 mJ/cm3 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 [Formula: see text] = 0.24 shows the maximum response with the coupling coefficient ([Formula: see text]) = 15.54 g2/emu2.
