Magnetoelastic effect in thin magnetic films at parametric excitation

The bending oscillations of the film-substrate system, explained by magnetostriction interaction, were observed at parametric excitation of thin magnetic films at the frequency 11 MHz. The frequency of the bending oscillations changed from 10
⁴
to 10
⁵
Hz. The dependences of the elastic modes on dc and HF magnetic fields affecting the film have been investigated. Some advice for the technical applications of the observed phenomenon is given in this paper.
