Transitions between different multivortex states and transitions between multivortex states and giant vortex states are observed in mesoscopic superconducting disks using the multiple-small-tunnel-junction method. These results are compared to theoretical calculations within the framework of the non

โฆ Synopsis
Submicron and micronsize type I superconducting disks are studied using the Ginzburg-Landau theory. An external perpendicular magnetic field may nucleate into a giant, vortex or, if the disk is sufficiently large, in multi-vortices.
The finite thickness (d) of the disk has a substantial influence on the giant vortex multi-vortex phase diagram.

We have studied vortex expulsion processes in a superconducting disk with a multi-terminal Hall sensor. Various combinations of these terminals enabled us to obtain an angular dependence of magnetization in the disk. The resolution of p/4 allowed us to identify three vortices. With a decrease in mag
Transitions between fluxoid states in asymmetric mesoscopic superconducting rings are investigated experimentally. We detected the fluxoid state transitions by the voltage change across current-biased small tunnel junctions attached to the ring. We found that the temperature above which the hysteres
The dynamics of vortex matter in mesoscopic superconducting Corbino disk is strongly influenced by the discrete vortex structure arranged in shells. While in previous works the vortex dynamics has been studied in large (macroscopic) and in very small mesoscopic disks (containing only few shells), in
