Consistency between domain wall oscillation modes and spin wave modes in nanostrips

扫码查看
Investigations on domain wall(DW)and spin wave(SW)modes in a series of nanostrips with different widths and thicknesses have been carried out using micromagnetic simulation.The simulation results show that the frequencies of SW modes and the corresponding DW modes are consistent with each other if they have the same node number along the width direction.This consistency is more pronounced in wide and thin nanostrips,favoring the DW motion driven by SWs.Further analysis of the moving behavior of a DW driven by SWs is also carried out.The average DW speed can reach a larger value of~140 m/s under two different SW sources.We argue that this study is very meaningful for the potential application of DW motion driven by SWs.
