We theoretically propose that magnetic skyrmion, nanometric spin vortexcharacterized by a quantized topological number, can be electrically created ona thin-film specimen of chiral-lattice magnetic insulator within a fewnanoseconds by applying an electric field via an electrode tip taking advantageof coupling between noncollinear skyrmion spins and electric polarizations.This finding will pave a route to utilizing multiferroic skyrmions asinformation carriers for low-energy-consuming magnetic storage devices withoutJoule-heating energy losses.
