Structural and dielectric properties of Y3/2Bi3/2Fe5O12

Abstract Polycrystalline Y 3/2 Bi 3/2 Fe 5 O 12 compound was prepared by a standard high-temperature solid-state reaction technique. Preliminary X-ray diffraction (XRD) analysis confirms the formation of a single-phase compound in a tetragonal crystal system at room temperature. The elemental composition of the prepared compound has been confirmed by energy dispersive X-ray spectroscopy (EDS) microanalysis. Microstructural analysis by scanning electron microscopy (SEM) shows that the compound has well defined grains, which are distributed uniformly throughout the surface of the pellet. Detailed studies of dielectric properties suggest that the compound has frequency dependent dielectric anomaly (with a shift in dielectric peak of different frequencies on increasing temperature).
