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.
