摘要
Standing spin-wave resonance spectra of metallic ferromagnetic films in parallel configuration are calculated analytically for the general cases of different external microwave field amplitudes and different surface anisotropies at the two film surfaces, and expressed in terms of a surface impedance matrix. Relations to the transfer matrix introduced by Vittoria in a similar context and examples of computed absorption spectra for two typical materials with different exchange-conductivity parameters are discussed.
