Abstract
We show that a magnetic vortex is the ground state of an array of magnetic particles shaped as a hexagonal fragment of a triangular lattice, even for an small number of particles in the array . The vortex core appears and the symmetry of the vortex state changes with the increase of the intrinsic magnetic anisotropy of the particle ; the further increase of leads to the destruction of the vortex state. Such vortices can be present in arrays as small in size as dozen of nanometers.
