Phase Modulation of Spin Waves via Surface Acoustic Waves — •Tim Vogel, Björn Heinz, and Philipp Pirro — Fachbereich Physik and Landesforschungszentrum OPTIMAS, RPTU Kaiserslautern-Landau

The interaction of spin waves and surface acoustic waves (SAWs) offers promising opportunities for advanced spintronic and magnonic applications. This study investigates the feasibility of using low-frequency SAWs in the MHz range to modulate the phase of high-frequency spin waves in the GHz range. Using micromagnetic simulations with mumax3, we investigate the dynamic coupling mechanisms and conditions necessary for effective phase manipulation of propagating spin waves.

While the primary focus is theoretical, this work also provides a framework for potential experimental validation to elucidate key factors such as coupling efficiency, propagation dynamics and system geometry. These results will contribute to a deeper understanding of magnon-phonon interactions.

We acknowledge funding by the European Union via Horizon Europe project MandMEMS, Grant No. 101070536.
