Controlled Separation of Skyrmions and Antiskyrmions by Kitaev Interaction.

As topological quasi-particles in magnetic materials, skyrmions and antiskyrmions show potential in spintronics for information storage and computing. However, effectively controlling and separating these entities remain significantly challenging. Here, we demonstrate that anisotropic Kitaev exchange can distinctly influence the static and dynamic behaviors for skyrmions and antiskyrmions, thus aiding their manipulation and separation.
