Abstract :
The effect of strong magnetoelastic interaction on spin-wave resonance-mode spectra in ferrite film-dielectric substrate planar structures is investigated experimentally and theoretically. Magnetoelastic effects are observed in the narrow range of the exchange magnetostatic wave (MSM) spectrum, and in frequency oscillations of the relaxation parameter expressed in frequency linewidth units, the linewidth, the MSM intensity, and the anomalous frequency dependence of the MSM resonance magnetic field
