Writing skyrmions with a magnetic dipole

We demonstrate numerically, through energy minimization on large spin lattices, that one can write skyrmions in a thin magnetic film with a magnetic dipole of a few tens of nanometer in size. Nucleation of non-chiral skyrmions as well as chiral skyrmions formed by the Dzyaloshinskii-Moriya interacti...
