Abrikosov vortex
In superconductivity, an Abrikosov vortex (also called quantum vortex or a fluxon) is a vortex of supercurrent in a type-II superconductor, used by Soviet physicist Alexei Abrikosov to explain magnetic behavior of type-II superconductors in 1957. Abrikosov vortices occur generically in the Ginzburg–Landau theory of superconductivity.
