摘要
The influences of uniaxial in-plane anisotropy on the properties of ordered magnetic structures generated by the DM interaction were investigated by performing Monte-Carlo simulated annealing. The uniaxial anisotropy aligns the magnetic structure along a specific direction and helps to organize magnetic skyrmions to form either a horizontal or a vertical hexagonal structure, depending on the anisotropy strength. The uniaxial in-plane anisotropy not only enhances the ordering of the structure but also enriches the phases of the system, which include a rectangular lattice structure of skyrmions and 1D skyrmion arrays separated by stripe domains. We investigate the formation conditions of the anisotropy strength and the external field for various magnetic phases.
