Abstract

We have investigated the zero field permeability behavior of Y-type hexaferrites. The measured permeability from 0.045 to 10 GHz was theoretically explained in term of zero magnetic field multi-domain and domain wall resonance. The basal plane anisotropy field, H/sub /spl phi///sup A/, domain wall thickness /spl delta/ and length L of the domain wall were estimated from resonance and permeability data.
