fluxoid

[′fluk‚sȯid] (solid-state physics) One of the microscopic filaments of magnetic flux that penetrates a type II superconductor in the mixed state, consisting of a normal core in which the magnetic field is large, surrounded by a superconducting region in which flows a vortex of persistent supercurrent which maintains the field in the core. Also known as flux line; fluxon; vortex.
