Abstract: The maximum amplitudes of elastic vibrations, depending on the material parameters and parameters of external fields in a normally magnetized anisotropic magnetic plate at its excitation by radio frequency magnetic field were obtained. For this purpose we used the method "simulated annealing". The threedimensional graphics of resonant surfaces of elastic oscillations on the thickness of the plate, on the elastic constants, magnetic damping constant and the magnetoelastic constant in the area of maximum amplitudes found by the simulated annealing algorithm were constructed and explained.

Keywords: magnetoelastic oscillations, ferrite plate, ferromagnetic resonance, simulated annealing.
