  We theoretically propose that magnetic skyrmion, nanometric spin vortex
characterized by a quantized topological number, can be electrically created on
a thin-film specimen of chiral-lattice magnetic insulator within a few
nanoseconds by applying an electric field via an electrode tip taking advantage
of coupling between noncollinear skyrmion spins and electric polarizations.
This finding will pave a route to utilizing multiferroic skyrmions as
information carriers for low-energy-consuming magnetic storage devices without
Joule-heating energy losses.
