Fully resonant magneto-elastic spin-wave excitation by surface acoustic waves under conservation of energy and linear momentum

We report on the resonant excitation of spin waves in micro-structured magnetic thin films by short-wavelength surface acoustic waves (SAWs). The spin waves as well as the acoustic waves are studied by micro-focused Brillouin light scattering spectroscopy. At low magnetic bias fields, a resonant pho...
