Experimental study demonstrates resonant magnon-to-chiral-phonon conversion in metallic magnetic thin films, highlighting crystal symmetry effects on angular momentum.
The magnetoelastic coupling of magnetic and elastic excitations enables the generation of elastic waves carrying angular momentum. In a quantum picture, this corresponds to a resonant conversion of magnons to chiral phonons and vice versa. This study showcases this conversion process using a simple and versatile experimental platform consisting of a metallic magnetic thin film on a crystalline substrate. These findings allow us to study the impact of crystal symmetry on angular momentum transport by phonons and investigate phononic birefringence.
