Abstract

we investigate the magnetization textures and the control possibilities in the moir pattern formed of twisted bilayer two-dimensional (2D) magnets CrX 3 (X=Br, I). We find that the stacking dependent interlayer magnetic interaction results in the formation of periodic magnetization domains in a long-period moir pattern. Magnetization textures with various topological numbers can be constructed, depending on the winding of the textures around the domain walls. A uniform external magnetic field competes with the lateral modulated interlayer magnetic interaction and can be utilized to tune the magnetization textures.
