Abstract

Here we studied the effect of homovalent Pr3+ and Y3+ substitution on the crystal structure, dielectric, electronic polarization and magnetic properties of the BiFeO3 multiferroic ceramic. The samples were synthesized by the conventional solid-state reaction method. Pure phase formation of Pr doped BiFeO3 (BFO) has been obtained, while Y3+ doped BFO has shown a few impurity peaks. It has shown that the crystal structure of the compounds is described within the space group R3c. Pr3+ modified BFO has shown an anomaly in the epsilon (r) vs. T plot around and a N,el temperature 'T (N)'similar to 370 C-a similar to. P-E hysteresis loops have shown higher value of remnant polarization for Pr3+ modified BFO. Magnetic properties of ceramics are determined by the ionic radius of the substituting element. Experimental results propose that the increase in the radius of A-site ion leads to effective suppression of the spiral spin structure of BiFeO3, resulting in the appearance of net magnetization.
