Skyrmion generation by current

Skyrmions, once a hypothesized field-theoretical object believed to describe the nature of elementary particles, became common sightings in recent years among several noncentrosymmetric metallic ferromagnets. For more practical applications of Skyrmionic matter as a carrier of information, thus realizing the prospect of "Skyrmionics," it is necessary to have the means to create and manipulate Skyrmions individually. We show through extensive simulation of the Landau-Lifshitz-Gilbert equation that a circulating current imparted to the metallic chiral ferromagnetic system can create isolated Skyrmionic spin texture without the aid of external magnetic field.
