SYNTHESIS AND CHARACTERIZATION OF ZINC FERRITE BY XRD, VSM AND ELECTRON SPIN RESONANCE TECHNIQUES

In this report, the synthesis of zinc ferrite (ZnFe2O4) by co-precipitation method has been presented along with its subsequent characterization by using X-ray diffraction (XRD), vibrating sample magnetometer (VSM) and electron spin resonance (ESR) techniques. The obtained XRD results of as-synthesized sample indicates the cubic spinel phase formation, which was confirmed from the XRD data of the above calcined sample at 1000°C. By using VSM, a complex magnetic structure was observed with substantial change on calcined sample. The ESR result of zinc ferrite sample studied at room temperature was found to be significantly different from that of the low temperature results, especially after heat-treatment.
