Frequency-dependent effective permeability tensor of unsaturated polycrystalline ferrites

Year: 2015

Type: article

Abstract: Frequency-dependent permeability tensor for unsaturated polycrystalline ferrites is derived through an effective medium approximation that combines both domain-wall motion and rotation of domains in a single consistent scattering framework. Thus derived permeability tensor is averaged on a distribution function of the free energy that encodes paramagnetic states for anhysteretic loops. The initial permeability is computed, and frequency spectra are given by varying macroscopic remanent field.
