ABSTRACT
Cobalt ferrite (CoFe2O4) is a spinel ferrimagnetic oxide with high saturation magnetization, large magnetocrystalline anisotropy. Highly crystalline cobalt ferrite particles have been prepared using a newsynthesis method i.e. microwave route. This microwave assisted route is one of the simplest and easy methods for synthesis. Here, cobalt ferrite (CoFe2O4) is prepared by microwave route using thermal decomposition of cobalt oxalate precursor. Urea is used as a fuel for the solid-state combustion reaction. In this article, we reportthe investigation of ac conductivity and dielectric behavior of cobalt ferrite in the frequency range of 1 KHz to 1MHz and in the temperature range of 00 to 7000 C. The obtained ac conductivity is found to be very low. The experimental results indicate an abnormal behavior in case of dielectric properties.
