Superconducting state in a circular SQUID shaped mesoscopic film

摘要

Using a thin-film approach to the time-dependent Ginzburg-Landau theory, we have studied the magnetization and order parameter profile in a thin mesoscopic superconductor in the so-called SQUID geometry. Our sample is circular with a hole at the center connected to the outer rim by a very thin slit. We have also studied the influence of
