Vortex state

The vortex state is a thermodynamic state of a material, characterized by co-existing resistive and superconducting sub-regions which form cores roughly 300 nm across. It is the state transitioned to by Type II superconductors when an external magnetic field first overcomes the Meissner current at the material's boundary.

It is still possible for material in the vortex state to be superconductive as long as the cores remain relatively stationary and/or there is a superconducting path through the material.
