Abstract

The superconducting state of mesoscopic square samples with two and four antidots is studied using the nonlinear Ginzburg-Landau (GL) theory. We found a qualitative difference in the nucleation of the superconducting state in samples with different number of antidots, which is related to the interplay of the different types of symmetry. The H-T phase diagram of these structures reveals an oscillatory behavior caused by the formation of different stable vortex configurations in these small clusters of pinning centers. A comparison with the experiment of H-T phase diagram is given.
