Coherent control of collective spin excitations (magnons) with acoustic phonons is a key technology for future hybrid spintronic devices, thanks to the short wavelengths and low radiation loss involved. However, a tiny coupling efficiency limits the controllability and functionality of devices. The authors develop a planar cavity-magnomechanical system and show coherent magnon-phonon transduction with a cooperativity exceeding unity. This approach paves the way for the development of alternative magnomechanical technologies for both quantum and classical applications.
