Abstract

The polycrystalline samples of Bi1-xPrxFeO3 (x = 0 and 0.1) were prepared by a solid-state reaction technique. Preliminary X-ray structural analysis has confirmed the formation of a single-phase compound. Studies of dielectric and impedance spectroscopy of the materials, carried out in wide frequency (1 kHz–1 MHz) and temperature (25–400 ℃) ranges, have provided many interesting results including significant decrement in tangent loss, structural stability, obeying Jonscher’s universal power law, etc.
