Topological analysis and experimental control of transformations of domain walls in magnetic cylindrical nanowires Open
Topology is a powerful tool for categorizing magnetization textures by defining a topological index in both two-dimensional (2D) systems, such as thin films or curved surfaces, and in 3D bulk systems. In the emerging field of 3D nanomagnet…
