Current‐Controlled Skyrmion Number in Confined Ferromagnetic Nanostripes
Current‐Controlled Skyrmion Number in Confined Ferromagnetic Nanostripes
Abstract Skyrmions are vortex‐like localized magnetic structures that possess an integer‐valued topological index known as the skyrmion number or topological charge. Skyrmion number determines the topology‐related emergent magnetism, which is highly desirable for advanced storage and computing devices. In order to achieve device functions, it is necessary to manipulate the …
