Abstract

In this paper, we have investigated the effect of Cr3+ substitution on the crystal structure, microstructure, dielectric and magnetic behavior of the morphotropic phase boundary (MPB) composition of the multiferroic ceramic 0.675BiFe(1−x)CrxO3–0.325PbTiO3 (x = 0, 0.02 and 0.05). The average grain size of the specimens increased from ~ 150 nm for x = 0 to 470 nm for x = 0.05. Rietveld refinement analysis of the X-Ray powder diffraction patterns confirmed the coexistence of multiphase i.e. monoclinic Cc and tetragonal P4 mm polymorphs for all the compositions. The system exhibits weak ferromagnetism for x = 0.05. We estimated the magnetoelectric interaction constant (γ ~ 0.31) for x = 0.05 by Ginzburg–Landau theory. The value of magnetoelectric coupling coefficient (
