Note that in type-II superconductors . The circulating supercurrents induce magnetic fields with the total flux equal to a single flux quantum . Therefore, an Abrikosov vortex is often called a fluxon.
It's worth noting that in type-II superconductors , the circulating supercurrents generate magnetic fields whose total magnetic flux equals just one quantum of magnetic flux. As a result, an Abrikosov vortex is frequently called a fluxon.
