Abstract <p>Micromagnetic simulation of group and individual one-dimensional ferromagnetic nanostructures was performed. The high aspect ratio of the ferromagnetic cylinders creates an anisotropic magnetic shape, facilitating the formation of longitudinal domains. On the other hand, circular symmetry enables one to utilize fewer common regions where the magnetic moments are not parallel to each other but move along a circle. All these features become even more pronounced in nanoscale wires.</p>
