Nonlinear dynamics of magnetoelastic oscillations in the amplitude modulation mode

Oscillations of the magnetization in a normally magnetized plate with magnoelastic properties, which occur under the influence of an amplitude modulated alternating field, are considered. The frequency of the variable field modulation is equal to the frequency of the acoustic resonance and is 10 times less than the carrier frequency. Significant differences are noted in the behavior of the magnetic and elastic subsystems, which depend on the type of polarization, as well as on the level of excitation.
