a Photothermal tweezing of an isolated single magnetic skyrmion (colored in red). b On-demand arrangement of skyrmions by a photothermal tweezer forming the patterns “KAIST” (upper panel) and “NQPL” (lower panel). Scale bar, 10 μm. c Probability of successfully transporting a single skyrmion over a 10 μm distance as a function of the incident laser power and sweeping speed vsw, based on 20 trials for each condition.
