(a) Calculated dependence of the total energy of the vortex and non-vortex state on the length of NWs. (b) The nucleation field of the vortex and the switching field for the vortex core as a function of NW length after saturation in 1 T parallel to the NW axis. (c) Simulated magnetization of single-crystal hcp Co NW with a 75-nm diameter, depending on the length of the NW.
