Intensity of the z component of the local magnetic field, normalized to the external applied field, along the x axis for several values of H. SQUID dimensions are 12 × 12 × 1 and the Ginzburg–Landau parameter is κ = 0.774 596 669.

Abstract: Using a genuinely tridimensional approach to the time-dependent Ginzburg–Landau theory, we have studied the local magnetic field profile of a mesoscopic superconductor in the so-called SQUID geometry, i.e., a square with a hole at the center connected to the outside vacuum through a very thin slit. Our investigation was carried out in both the Meissner and the mixed state. We have also studied the influence of the temperature on the space distribution of the local magnetic field.
