Periodic magnetic domains on cobalt filaments can be stabilized by nanoscale corrugations on the surface, which are spontaneously generated by a unique electrodeposition method. The type of magnetic domains varies from anti‐parallel single domains to vortex domains depending on the ratio of the spatial periodicity of the corrugations and the filament width (see figure), and can be experimentally tuned.
