Controllable interskyrmion attractive interactions and resulting skyrmion-lattice structures in two-dimensional chiral magnets with in-plane anisotropy

We study inter-skyrmion interactions and stable spin configurations in a 2D chiral magnet with in-plane anisotropies of tilted magnetic field the magneto-crystalline anisotropy on (011) thin film. find that both cases small deformation skyrmion shape makes interaction anisotropic, skyrmions are weakly bounded along certain direction due to an emergent attractive interaction. Furthermore, when is comparable Zeeman energy, embedded uniform magnetization tightly bound by creating domain between them. The formation domain, thus strength interaction, can be controlled external field. anisotropic also affects alignment crystal (SkX) phase. By employing Monte Carlo simulation micromagnetic simulation, we obtain elongated triangular lattice structure SkX In particular, presence strong anisotropy, domains appear background structure, bimerons aligned walls form lattice. parameter region phase stabilized attraction.
