Abstract :
The motion of magnetic skyrmions driven by propagating spin waves (SWs) in a skyrmion-based magnetic nanotrack is investigated by means of micromagnetic simulation. It is found that the propagating SWs can drive the skyrmion into a stream motion. The velocity of the skyrmion motion is controlled by the changes of SWs frequency and exciting field amplitude, which is sensitive to the size of skyrmion.
