From: Current-induced viscoelastic topological unwinding of metastable skyrmion strings
Schematics of the emergent magnetic monopole and antimonopole. a, b Monopoles/antimonopoles resulting from the pinching-off of a skyrmion string (a) and partial merging of two neighboring skyrmion strings (b). Colored circles represent emergent magnetic monopoles/antimonopoles. Arrows indicate expected motions of the monopoles/antimonopoles when the topological unwinding progresses
