L-TEM images showing the skyrmion motion after turning on the electric current of 32 mA for the different time periods, respectively. The blue circle for the fixed defect is marked out to identify the relative movement of the skyrmions on the domain wall. The relative movement of the three skyrmions is demonstrated with different colors, respectively.
