Dynamic permeability of ferromagnetic thin films with stripe domain structure

Summary form only given. A relationship constraining the static permeability and resonance frequency of thin ferromagnetic films has been established recently. This relationship is great importance in view of the problem of developing the materials possessing high permeability at microwaves. But the relationship is of limited applicability, being derived for a single domain film with uniaxial inplane anisotropy only. This paper deals with more practical occasion, where the effect of the stripe domain structure and of out-of-plane magnetic anisotropy on the dynamic permeability of a ferromagnetic thin film.
