Acoustically driven magnons in CrSBr bilayers

Year: 2026

Type: article

Abstract: We study the coupling between spin excitations and acoustic waves in bilayers of CrSBr, an ambiently stable two-dimensional (2D) magnetic material. We demonstrate that a strong dependence of interlayer 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.
