Dielectric and magnetic studies of nano-sized CoNiZn ferrite prepared from combustion synthesis

Abstract

Synthesis of CoNiZn ferrite by combustion method was carried out using Maleic acid as a novel fuel. Thermal decomposition temperature for combustion synthesis was fixed using TG-DTA studies. Characterization of synthesized compound was done by X-ray diffraction studies. Average crystallite size was found out using Scherrer formula. Dielectric constant was measured as a function of applied frequency in the range from 20 Hz to 1 MHz at varying tempearture. Temperature dependent magnetization studies as ZFC-FC measurements were carried out at different applied fields.
