COMPLEX PERMEABILITY SPECTRA OF MANGANESE-ZINC FERRITE AND ITS COMPOSITE

Rastislav Dosoudil - Vladimír Olah

   The magnetic permeability spectra of an Mn-Zn sintered ferrite and its composite have been studied. The model based on the relaxation-type spin resonance formulation combined with the magnetic circuit model for ferrite magnetocomposites was proposed. The relevance of this model has been verified by measuring of the complex permeability of the composite and compared to the properties of the sintered ferrite. The observed relaxation frequencies of the composite are much higher than those of the sintered material.

Keywords: complex permability, composite magnetic material, magnetic circuit, spin resonance, sintered ferrites
