Non-reciprocal Pumping of Surface Acoustic Waves by Spin Wave Resonance
(JPSJ Editors' Choice)
J. Phys. Soc. Jpn. 89, 113702 (2020).
The coupling between surface acoustic waves and spin waves is shown to depend strongly on the angle between the acoustic wavevector and magnetization. For a particular angle, it completely vanishes in one direction, which enables a unidirectional generation of surface acoustic waves by a ferromagnetic resonance.
