In superconductivity, a Pearl vortex is a vortex of supercurrent in a thin film of type-II superconductor, first described in 1964 by Judea Pearl. A Pearl vortex is similar to Abrikosov vortex except for its magnetic field profile which, due to the dominant air-metal interface, diverges sharply as 1/ r at short distances from the center, and decays slowly, like 1/ r 2 at long distances. Abrikosov's vortices, in comparison, have very short range interaction and diverge as log ⁡ ⁡ ( 1 / r ) near the center.
