(a) Magnetic structure of the stripe domain and (b) skyrmion lattice domain. The black-and-white scales show the out-of-plane part of the magnetization and the arrows show the in-plane part of the magnetization of a grid at the location of the arrows. (c) Change of magnetic structure with increasing external field. The field strength is 0.0, 0.2, 0.4, 0.6, and 0.9J/ς² from left to right.
