Structural, Magnetic and Dielectric Properties of Ni0.3Cu0.7CoxCrFeO4 Sol-gel Synthesized Nano Thin Films

Abstract

A thin magnetic oxide layer with composition Ni0.3Cu0.7CoxCrFeO4 (0.0<x<1) is produced by the SILAR process. X-ray diffraction, cation distribution and infrared spectra were investigated as structural features. Permittivity and dissipation factor are properties of interest. Magnetic properties were studied using MOKE. The lamellae have been shown to have spinal structures. As Co grows, the lattice constant also increases. Observed I.R. spectra show tetrahedral and octahedral bonds. Increase in the dielectric properties because enhancement of space charge polarization.
