Dataset description

Surface acoustic waves (SAWs) have significant potential for the energy-efficient control of magnetic domain walls (DWs). This study investigates the influence of SAW frequency (50, 100, and 200 MHz) on DW dynamics in magnetic thin films. Micromagnetic simulations are performed to examine the effects of SAWs on DW velocity. The results demonstrate that SAWs enhance DW motion by promoting the depinning of DWs from pinning sites through SAW-induced spin rotation. This spin rotation exhibits the same frequency as the applied SAWs. The impact of SAW frequency varies depending on the level of anisotropy disorder in thin films. In films with 3% anisotropy disorder, the DW velocity increases with SAW frequency, highlighting the amplifying effect of spin rotation and enhanced DW depinning. Conversely, in thin films with 1% anisotropy disorder, the DW velocity decreases with SAW frequency owing to significant SAW-induced energy dissipation via spin rotation. These findings underscore the intricate interplay between SAWs, spin rotation, and DW dynamics, emphasizing the role of anisotropy disorder in governing the response of DWs to SAWs. The study contributes to the understanding of SAW-assisted DW motion and provides insights into the optimization of and energy-efficient control of DWs in spintronic applications using SAWs.
