Structural and magnetic properties of Cr-Substituted NiCuZn ferrite

Abstract

Cr-substituted Ni0.2Cu0.2Zn0.6Fe2-xCrxO4 ferrites (where x = 0-1.0) were prepared by solid-state reaction. The effects of Cr content on structural and magnetic properties were investigated. X-ray diffraction (XRD) revealed the formation of ferrite particles with cubic spinel structure. The lattice parameter and average crystallite sizes are much dependent on the chromium content and are found to decrease with its increasing. The initial permeability (μi) and saturation flux density (Bs) decrease with the increasing Cr content. In addition, without substituted ceramic samples possess lower quality factor (Q factor) than the NiCuZn ferrites with Cr substituted.
