We investigate the nucleation of superconductivity in a uniform perpendicular magnetic field H in aluminum microsquares containing a few (2 and 4) submicron holes (antidots). The normal/superconducting phase boundary Tc(H) of these structures shows a quite different behavior in low and high fields. In the low magnetic field regime fluxoid quantization around each antidot leads to oscillations in Tc(H), expected from the specific sample geometry, and reminiscent of the network behavior. In high…

Vortex Confinement Phenomena in Mesoscopic Superconductors
We report on vortex confinement phenomena in mesoscopic superconducting samples of different connectivity: singly connected dot, dot with two microholes (“antidots”) and dot with four antidots. For…

SUPERCONDUCTING STATE OF A PERFORATED MESOSCOPIC DISK WITH A SQUARE OR TRIANGULAR TRENCH
In this paper, we report on the influence of a square (triangular) trench on the superconducting properties of a perforated mesoscopic sample. Effects associated to the pinning force of the hole…
Nucleation of superconductivity in a mesoscopic rectangle
We have studied the nucleation of superconductivity in a mesoscopic rectangle. We used an analytical gauge transformation for the vector potential A which gives An = 0 for the normal component along…
