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 o
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
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
