Magnetoelastic Resonance in Zero-Mean Magnetostrictive Media
The interaction between two wave fields of different nature that are caused by rms fluctuations of the coupling parameter between these fields in media with zero-mean coupling parameter is considered. Taking into consideration the multiple scattering processes of waves on the inhomogeneities leads to the results considerably different from those that have been obtained for the same situation in the Bourret approximation earlier [4,5]. Instead of the degeneration removal of frequencies in the wave spectrum and the appearance of two resonance peaks in the dynamic susceptibility at the intersection of the initial dispersion laws, the sharp broadening of the self-mode peak has to be observed. The consideration is done by the example of magnetoelastic waves in zero-mean magnetostrictive media.
