Abstract

The polycrystalline sample of BiFeW2O9 was synthesized using a high-temperature (770 o C) solid-state reaction method. The formation of a single-phase compound was confirmed by preliminary X-ray structural studies of the material. The SEM micrograph of the compound showed uniform growth of grains with some small number and size of voids suggesting the formation of high-densification homogeneous sample. Detailed studies of dielectric and electrical impedance (impedance, electric modulus and conductivity) properties of the system in a range of frequency (1 kHz -1 MHz) and temperature showed that these properties are strongly dependent on temperature and frequency. The nature of frequency dependence of ac conductivity follows the Jonscher’s power law. The temperature dependence of dc conductivity pattern follows the Arrhenius behavior. The J-E characteristic shows the non ohmic conductivity of the sample.
