Abstract
The superconducting state of a thin mesoscopic superconducting ring surrounded by a medium which enhanced its superconductivity near the boundary is investigated by the phenomenological Ginzburg-Landau theory. The free energy, the Cooper-pair density, and the current density as well as the H–T phase diagram are investigated for a ring with different surface enhancement or for different rings with the same surface enhancement. It is also found that the stable multivortex state can occur in the small ring that we studied if the enhanced surface superconductivity is stronger, and the stable (1:L2) and (2:L2) states can exist as the ground states with increasing the inner radius.
