Simulations snapshots of spin systems of size L×L=3 for different parameter values and temperatures with the parameter D/Jchosen such that the pitch length p=8. The periodic boundary is drawn as a red solid line and spin vectors are represented by colored arrows where the color scales linearly with the zˆ component of the vector to highlight spin texture
