Abstract
- Abstract: The dynamics of the magnetization in the ferrite film close to the nonlinear magnetoacoustic resonance (MAR) for different magnitudes of the magnetic dissipation parameter is investigated. The interval of the magnetic dissipation parameter magnitudes, in which the nonlinear relaxation and strong damping of the magnetization is observed, is defined. The regime of the magnetoelastic autooscillations is observed if there is some detuning of the acoustic eigenfrequency from the MAR frequency in certain intervals of values of the alternating field amplitude during its action.
