We investigated the sample size dependence of the types of vortex states, i.e., multivortex states or giant vortex states, in mesoscopic superconducting squares by using the temperature dependence of vortex expulsion fields. The giant vortex states a

Mesoscopic superconducting disks are versatile systems to study different aspects of phase transitions. In such systems one finds giant to multivortex transitions and different vortex configurations for the same vorticity. The system exhibits metasta

The one vortex entry in a superconducting disk is investigated within the non-linear Ginzburg–Landau theory near the first critical field. We find that in mesoscopic superconducting disks the magnetic flux enters with fractions of one flux quantum

The distribution of the electric charge density in mesoscopic superconducting disks and cylinders is studied within the phenomenological Ginzburg-Landau approach. We found that even in the Meissner state the mesoscopic sample exhibits a non-uniform c

The superconducting state of a thin superconducting disk with a hole is studied within the non-linear Ginzburg-Landau theory in which the demagnetization effect is accurately taken into account. We find that the flux through the hole is not quantized

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 f

The vortex configuration during the penetration of the first vortex in asymmetric superconducting rings is investigated theoretically within the framework of the nonlinear Ginzburg–Landau theory. This state appears as a one-dimensional vortex state

Vortex states in mesoscopic superconducting spheres are investigated within the framework of the phenomenological Ginzburg-Landau theory in the presence of an externally applied magnetic field. We treat the linearized first Ginzburg-Landau equation a

Multi-quanta, or giant, vortices (GVs) are known to appear in very small superconductors near the superconducting transition due to strong confinement of magnetic flux. Here we present evidence for a new, pinning-related, mechanism for the formation
