Abstract
Effect of Sintering Temperature on the Structural Magnetic and Electrical Properties of Zinc Ferrite Samples
Zinc ferrite was synthesized by sol–gel method. Fine particles with different grain size were obtained by subsequent heat treatment at different temperatures. The structure of all the prepared samples was elucidated using XRD. Magnetic measurement shows a decrease in magnetization with increase in sintering temperature. The variation of AC conductivity and dielectric constant was studied as a function of frequency, temperature and grain size. The Maxwell-Wagner two layer model and electron hopping mechanism was used to explain the variation of conduction and polarization with frequency. The observed high permittivity and conductivity for small grains were explained on the basis of the correlated barrier hopping model.
