Though reliable control of skyrmion motion is essential for the operation of spintronics devices, the straight motion of skyrmions along the driving force is in general difficult due to an inevitable transverse force originating from their topology. Here, we propose a method of precise manipulation of skyrmions based on surface acoustic waves (SAWs) propagating in two dimensions. Using two standing SAWs, saddle-shape local potentials like quadrupole ion traps are created to trap skyrmions robustly. Furthermore, by tuning the frequencies of the SAWs, we show that trapped skyrmions not only move in straight lines but also move precisely Scientific reportsTrapping and manipulating skyrmions in two-dimensional films by surface acoustic waves.PMC9895437JPMJFR203HJP22H05449JP21J20969JP21H01794Shiomi YMiyazaki YYokouchi TfalseTrapping and manipulating skyrmions in two-dimensional films by surface acoustic waves.Skyrmions, topologically stable spin structures with particle-like properties, are promising for spintronics applications such as skyrmion racetrack memory.
