From: Skyrmion lattice domain formation in a non-flat energy landscape
a In a simulation of 5000 particles at density 1.25, we introduce 40 randomly spread angle-shaped patterns (green) with an energy −7.5 kBT with respect to the flat background potential. Throughout a simulation run, the domain boundary probability map remains inhomogeneous with regions of high occurrence probability around and between the angle patterns. b Snapshot of the local lattice orientation α per skyrmions after 100 STU. Distinct domains of different α form. The orientation changes in regions, where also the overall domain boundary occurrence probability is high. While some of the angle patterns (green) mark domain boundaries, others are located within a lattice domain.
