    We propose a device where an input spin wave is amplified parametrically by a travel acoustic wave. At the same time, a frequency conversion can be achieved by making use of the generated Idler spin wave.

    arXiv.2309.04987

    A proof-of-concept study which shows that surface acoustic waves can resonantly drive the gyrotropic motion of a vortex core via magneto-elastic interaction. An analytical model based no the Thiele approach is validates using full micromagnetic simulations.
