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 TiO2 content 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
