Skrymions are topological spin textures in chiral magnetic materials and can provide new possibilities for next-generation devices. Real-space Berry curvature can play an important role in controlling the motion of skrymions. Here, we introduce ways to measure Dzyaloshinskii–Moriya interaction, which is closely related to the formation of skrymions, and to determine atomic positions by using X-ray scattering. We also review brief studies on skyrmions in two-dimensional (2D) magnetic heterostructures and the Moiré of van der Waals 2D magnets.
