| contents | We study the coupling between spin excitations and acoustic waves in bilayers of CrSBr, an ambiently stable 2D magnetic material. We demonstrate that a strong dependence of inter-layer exchange coupling on strain makes possible the resonant generation of magnons by an acoustic wave. It is shown that the parameters of the generation, in particular the resonant frequency, can be tuned by an external magnetic field, which makes CrSBr a promising platform for spintronics applications. |
