Abstract

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.

磁膜的各向异性对调幅磁场激励下磁弹性场检测的影响

摘要

考虑在磁性薄膜的弹性子系统上检测幅度调制的磁性线性极化交变场。研究了各向同性薄膜和具有不同立方各向异性易轴相对于法线取向的薄膜的磁化矢量振荡和弹性位移动力学。构建了磁化矢量分量振荡的参数模式以及磁化和弹性位移的激发振荡的频率特性。确定了磁性膜弹性位移的振荡模式对交变磁场强度的幅度和调制指数的依赖性。
