The Effect of Cerium Substitution on Electromagnetic Properties of NiZn Ferrites

Abstract:

An extensive investigation of electromagnetic properties has been carried out on the CeO₂-doped NiZn ferrites, (Ni_0.44Zn_0.56Fe₂O₄), prepared by solid-state reaction technique. X-ray diffraction (XRD), scanning electron microscopy (SEM), and LCR meters were used to analyzed the ceramic phase, microstructure, permeability, permittivity, and quality factor. The results show that the real dielectric constant increases by proper amount of CeO₂ substitution, and the magnitude of this increase is not linear with the content of CeO₂. Initial permeability decreases with the increasing Cerium content. The quality factor reaches the maximum value (194 at 1 MHz) when the added CeO₂ content is 2.0 wt%. CeO₂ substitution increase the resistivity of NiZn ferrites.
