Abstracts

The microwave surface impedance of conductive ferromagnetic films hypothetically deposited on dielectric, metal and superconducting substrates was numerically investigated for the case when the film is tangentially magnetized. It was shown that the surface impedance is governed by the ferromagnetic film conductivity if the film is thin enough. Peculiarities of the impedance caused by the ferromagnetic resonance arise more clearly in thicker ferromagnetic films or in films deposited on substrates of higher permittivity or on metal and superconducting substrates. A ferromagnetic film strongly affects the surface impedance of superconducting material, especially, in the ferromagnetic resonance frequency region.
