Parametric Excitation and Instabilities of Spin Waves Driven by Surface Acoustic Waves

Parametric Excitation and Instabilities of Spin Waves Driven by Surface Acoustic Waves

Abstract The parametric excitation of spin waves by coherent surface acoustic waves in metallic magnetic thin film structures is demonstrated experimentally using Brillouin light scattering spectroscopy. Complementary micromagnetic simulations and analytical modeling reveal that, depending on the ex...
