Abstract: Excitation of hypersound elastic oscillations in the microwave on the magnetization reversal of the normal magnetized ferrite plate is studied in the paper. Characteristic times of the process of development of magnetic and elastic oscillations were revealed. Their relation to the parameters of the magnetic and elastic damping has been revealed.

Abstract: The present work deals with investigation of features of a magnetization vector of nonlinear precession and elastic displacements close to ferromagnetic resonance in normal magnetized ferrite plate. The system of ordinary differential equations was solved numerically by the Runge-Kutta 7-8 orders method with control of the integration at every step length. The possible excitation of magnetoelastic autooscillations was found out in the paper. Two mechanisms of autooscillations: reorientation and detuning were investigated. The boundaries between the regular and chaotic reorientation autooscillations depending on the magnetic dissipation parameter and magnetoelastic interaction constant were determined.
