Abstract:The Dzyaloshinkii-Moriya (DM) interaction that originates from relativistic spin-orbit coupling in noncentrosymmetric magnets is a source of topological spin textures. We theoretically investigate the possibility of a skyrmion crystal by focusing on the role of the out-of-plane DM interaction that is different from the polar-and chiral-type DM interaction. By performing the simulated annealing for a spin model on a triangular lattice belonging to the D 3h point group, we construct low-temperature magnetic phas… Show more
