Abstract

[(BiFeO₃)_y(BiMg_0.5Ti_0.5O₃)_1-y]_x[PbTiO₃]_1-x (BF-BMT-PT) ceramic powders were prepared by high temperature solid-state reaction method. X-ray diffraction analysis of the powders suggests the formation of a single-phase material with tetragonal structure. SEM images exhibit the uniform distribution of grains. Polarization vs electric field (P-E) hysteresis studies show maximum remanent polarization (P_r ∼ 14 μC/cm²) for composition X = 0.65. Dielectric studies of the compounds as a function of temperature (from RT to 550 °C) (test frequency 100 kHz) show that the compounds undergo a diffuse phase transition with a transition temperature increasing with decreasing X. The diffusivity parameter of the phase transition for these compounds yielded values between 1.6 and 1.8 indicating significant variation of degree of disordering in the system.
