Abstract

Skyrmion Motion Understanding skyrmion motion is essential for the efficient operation of skyrmionic devices. In article number 2203275, Chanyong Hwang, Kyoung-Whan Kim, Albert Min Gyu Park, Kab-Jin Kim, and co-workers uncover a universal scaling behavior in the current-driven motion of skyrmions. The topology of the shape of the interface drags the skyrmions and causes them to show hopping properties distinct from the creep motion expected for magnetic domains. The universal scaling can provide insights for implementing skyrmion devices and understanding the dynamics of moving bodies with a closed interface.
