Fig. 3: Zigzag-type skyrmion trajectory.

a The MOKE microscope images depict how skyrmion bubbles with opposite helicity numbers respond when injecting the current pulses along the +x axis. b Zigzag-type trajectories of the skyrmion bubbles, with colored triangles indicating their center positions throughout the pulse series from (a). The skyrmion bubbles are represented by red and blue triangles within the images. The pulse is set with a duration of 20 μs and amplitude of 49.4 mA (2.09 × 1011 A/m2). The pulse interval was set to 30 μs to achieve the zigzag-type trajectory. The scale bar is in 5 μm.
