The vortex state is a thermodynamic state of a material, characterized by co-existing resistive[1] and superconducting sub-regions which form cores roughly 300 nm across.[2][3] 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. File:Position memory due to pinning in a superconductor.ogv 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.
