Magnetic Bubble Domain Blowing with Electric Probe

Abstract

The problem of bubble domain generation is revisited from a new perspective that was opened by recent findings in the field of physics of magnetic skyrmions. The single bubble domain can be generated under the tip electrode touching the surface of dielectric iron garnet film by positive step-like voltage pulse and its equilibrium size can be increased with further rising of electric potential. The theoretical analysis shows that the same mechanism can be used to stabilize the submicron bubbles topologically equivalent to the skyrmion.
