Abstract: For a superconducting mesoscopic square loop of intermediate size, comparable with the coherence length and with the penetration depth, the superconducting state is described and the phase boundaries are analyzed on the basis of a self-consistent solution of the Ginzburg-Landau equations. As a heuristic criterion for the phase boundary, the appearance of a "superconducting path" between the links of the leads with the loop is proposed in fair agreement with experiment. The magnetization, deduced for states away from the phase boundary, reveals a quasi-oscillating behaviour. as a function of the applied magnetic field.
