摘要: We study domain-wall (DW) motion induced by spin waves (magnons) in the presence of Dzyaloshinskii-Moriya interaction (DMI). The DMI exerts a torque on DW when pass through DW, and this represents linear momentum exchange between wave DW. Unlike angular waves, leads to rotation plane rather than motion. In an effective easy anisotropy, transfer mechanism is significantly more efficient moving
