Abstract

The problem of excitation of ferromagnetic resonance in a thin ferrite film with magnetoelastic properties located on a thick elastic substrate is considered. A model is proposed for the excitation of elastic modes in the substrate due to the propagation of a periodic boundary regime created by magnetic oscillations in the film. The conditions for stationary oscillations are used to obtain the frequency response characteristics of ferromagnetic resonance, which exhibit strong oscillations due to the excitation of high-order elastic modes over the thickness of the substrate.
