摘要
A magnetic vortex wall motion driven by propagating spin waves in a nanostrip is investigated by means of micromagnetic simulation. Propagating spin waves can drive a vortex wall into a stream motion in spite of its complex internal spin structure. Compared to the transverse wall, the vortex wall moves faster and its velocity is less sensitive to the spin wave frequency. The amplitude of spin waves changes when passing through the domain wall, closely related to the domain wall velocity. This domain-wall-type-specific study provides important information for developing the theory of the interaction between domain wall and spin waves.
