Analysis on Permeability Spectra of Manganese-Zinc Ferrites with Fe-poor Composition

doi:10.3724/SP.J.1077.2007.00474

Abstract

Abstract: MnZn ferrites and NiZn ferrites were prepared by conventional ceramic processing techniques. The frequency dependence of permeability of MnZn ferrites with Fe-poor composition (less than 50mol% of Fe₂O₃) was studied. Tri-segment frequency dispersion model which consists of domain wall motion, magnetization rotation and gyro-magnetic spin rotation was used to simulate the permeability spectra of ferrites. Effects of Fe₂O₃ and TiO₂content on
permeability of Fe-poor MnZn ferrites were also studied to analyze contribution of the simulating parameters.

Key words: MnZn ferrites, Fe-poor, permeability spectra
