Diffusive skyrmion motion on an asymmetric nanoisland including a defect. z component of the magnetization (white +z, black −z) is imaged. In the top-left corner, a defect is modeled by freezing the magnetization direction in a single simulation cell along the +x direction. a Snapshots of the magnetization at different times, as well as the resulting time-averaged picture (av.). Scale bar corresponds to 10 nm. b Time-averaged signal along the dashed arrow shown in the lower right part of a. Simulation box: 30 × 30 × 0.4 nm3, T = 25 K, B = 1.5 T. The saturation magnetization is locally set to zero in the dark gray areas
