摘要：
Ba0.5Bi0.5Ti0.5Fe0.5Mn0.1O3, a Fe-based Mn-modified BFO-BT ceramic, is processed by solid-state reaction route, calcined at 950 degrees C temperature. Formation of single-phase orthorhombic structure is observed from room temperature XRD analysis. Dielectric behavior is investigated over a broad range of temperature (30 degrees C-500 degrees C) and frequency (0.1 kHz-10 MHz). Broadening of transition temperature is noticed at 460 degrees C, where the material undergoes a change from ferro- to paraelectric state. From dielectric plots the effect of Mn on capacitive behavior of the material is studied. The conductivity study exhibits negative temperature coefficient of resistance (NTCR) behavior showing semiconducting behavior of the material.
