Abstract
Low magnetic property is one of the major disadvantages of bismuth ferrite which limits its industrial utility. We have substituted bismuth from bismuth ferrite by antimony to solve the limitations of the material. Polycrystalline samples of SbFeO3 and BiFeO3 are prepared by solid-state reaction technique. Crystal structure investigation of both the compounds are carried out by X-ray diffraction (XRD). The crystallite sizes obtained from XRD data are 49 nm for SbFeO3 and 62 nm for BiFeO3. The impedance and dielectric studies of the materials are carried out at various frequency (102–106 Hz) in a wide temperature range (30–475 °C). Dc conductivity and ac conductivity of both the materials are explained by Arrhenius relation and Jonscher’s universal power law, respectively. Leakage current of SbFeO3 is found to be large compared to BiFeO3.
