Abrikosov Vortex

An Abrikosov vortex is a tiny magnetic whirl in a type-II superconductor, which occurs when a magnetic field penetrates the material. Unlike in regular superconductors that expel all magnetic fields, type-II superconductors allow magnetic lines to pass through in discrete, quantized tubes called vortices. Each vortex carries a single quantum of magnetic flux and has circulating electrical currents around it. These vortices form an organized lattice, enabling the superconductor to carry high currents without resistance while accommodating magnetic fields. This phenomenon is key to understanding and utilizing advanced superconducting technologies.
