Magnetoelastic interaction in an epitaxial yttrium iron garnet film
Abstract
Experiments are reported in which hypersound was generated by a magnetostrictive transducer based on an epitaxial single-crystal yttrium iron garnet film. The thickness of the film was equal to half the wavelength of the generated acoustic wave. The principal characteristics of the transducer, measured by the echo method, are presented. A widening of the ferromagnetic resonance line due to a coupling between magnetostatic and elastic modes was observed.
