Magnon-mechanics in high overtone acoustic resonators — •Hans Huebl — Walther-Meißner-Institut, Bayerische Akademie der Wissenschaften, Garching, Germany — School of Natural Sciences, Technische Universität München, Garching, Germany — 3Munich Center for Quantum Science and Technology (MCQST), Munich, Germany

Magnetoelastic coupling between excitation modes of the spin system (spin waves) and the lattice (phonons) is of interest from a fundamental perspective and can enable mode hybridization. For quantum sensing and transduction protocols, excitation exchange between the magnetic and elastic systems is of importance, however typically this requires strong coupling between the modes. In this presentation, I will present our current results on coupling the magnetization dynamics of a Kittel mode to a high-overtone bulk acoustic resonator and discuss this hybrid system in the context of sensing and transduction.
