Abstract
We have investigated the permeability at microwave frequencies of Y-type hexaferrites in zero-magnetic field. The permeability was measured from 0.045 to 10 GHz and it was correlated with multidomain and domain-wall resonances in zero-magnetic field. The basal plane anisotropy field, HφA, magnetic remanence, 4πM, domain-wall thickness δ, and length L of the domain wall were estimated from resonances and permeability data.
