摘要
The importance of topological spin textures(TSTs), such as skyrmions, merons, hopfions, etc., is due to their static and dynamic properties [1]. They carry a topological number that characterizes the homotopy group Π_(n)(S^(2))(n ∈ Z) and classifies maps from S^(n) to S^(2)(e.g., the skyrmion winding number corresponds to Π_(2)(S^(2))).
