Influence of the Anisotropy of Magnetic Films on the Detection of Magnetoelastic Fields upon Excitation by an Amplitude-Modulated Magnetic Field

The detection of an amplitude-modulated magnetic linearly polarized alternating field on the elastic subsystem of a magnetic film is considered. The dynamics of oscillations of the magnetization vector and elastic displacement of an isotropic film and films with different orientations of the easy axes of cubic anisotropy with respect to the normal is studied. Parametric patterns of oscillations of magnetization vector components and frequency characteristics of excited oscillations of magnetization and elastic displacement are constructed. The dependence of the oscillation modes of the elastic displacement of the magnetic film on the amplitude of the alternating magnetic field strength and the modulation index is determined.
