Flux Confinement in Mesoscopic Superconductors
Y. Bruynseraede, V. V. Moshchalkov
Abstract
We report on flux confinement effects in superconducting submicron line, loop and dot structures. The main idea of our study was to vary the boundary conditions for confinement of the superconducting condensate by taking samples of different topology and, through that, modifying the lowest Landau level ELLL(H). Since the critical temperature versus applied magnetic field Tc(H) is, in fact, ELLL(H) measured in temperature units, it is varied as well when the sample topology is changed. We demonstrate that in all studied submicron structures the shape of the Tc(H) phase boundary is determined by the confinement topology in a unique way.
