摘要：

The high-frequency permeability of NiZn ferrite films prepared by roll spray ferrite plating is investigated. Significant magnetoelastic effects are observed. The permeability is nearly isotropic in film plane, and Bouchaud-Zerah effective medium model for the permeability seems to give a fair account of the permeability spectra. According to this model, the isotropic in-plane complex permeability is the square root of the hard axis gyromagnetic permeability of a thin film with uniform magnetization, which is easily expressed through Landau-Gilbert formulation.
