Abstract

In/Cr substituted Ni-Zn ferrites were prepared by standard solid state reaction method using metal oxides to estimate the influence of substitutions on the magnetic properties of the Ni-Zn ferrites. The ultrafine ground powders of the ferrite compositions were pressed into desired shapes and sintered at 1250C for 4 hours in air atmosphere. X-ray diffraction analyses of the samples confirm formation of single phase cubic spinel structures. Magnetic hysteresis loop measurements on the samples were made to study the magnetization behaviour and the obtained results indicate that the In/Cr substitutions cause a decrease in magnetization with the increase in substituent?s concentration. Initial permeability of the substituted ferrites exhibits stable frequency response up to 3 MHz beyond which it exhibits a relaxation character while the relative loss factor has been found to be quite low up even up to the frequency of 40 MHz while indicating their utility as elements for high frequency application systems.
