摘要：

Ferromagnetic resonance (FMR) and spin-wave resonances (SWRs) have been studied in transmission of an electromagnetic wave through the plate of ferromagnetic metal and in reflection from the plate. The method of calculation of the resonance phenomena has been developed which allows one to study the influence of spin pinning conditions on the amplitudes of eigenmodes. The spatial distribution of eigenmodes is investigated under FMR, SWR and magnetic antiresonance conditions. The transmission coefficient of Fe19Ni81 permalloy films measured as a function of the magnetic field agrees well with the calculated values.
