Abstract A simple variational model is proposed to analyze the superconducting state in long cylindrical type-II superconductor placed in the external magnetic field. In the framework of this model, it is possible to solve the Ginzburg–Landau (GL) equations for the states with axially symmetric distributions of the order parameter. Phase transitions between different superconducting states are studied in the presence of external magnetic field and an equilibrium phase diagram of thin cylinder… Expand

The lower critical field Hc1cyl(T) of a superconducting cylinder with radius r0∼ξ(T)≪λ(T) is found on the basis of the Ginzburg-Landau theory with various boundary conditions. These results togetherExpand
Effect of sample topology on the critical fields of mesoscopic superconductors
THE superconducting state of a material can be suppressed by either increasing the temperature (T) or applying a magnetic field (H). For bulk samples, the form of the H–T phase boundary is mainlyExpand
Simple model for the vortex core in a type II superconductor
In order to model the core of an isolated vortex in a type II superconductor, a variational trial function for the magnitude of the normalized order parameter of the form f = ϱ/R is assumed, where ϱExpand

Non-quantized penetration of magnetic field in the vortex state of superconductors
The amount of flux introduced by individual vortices in a superconducting film is measured, finding that the flux always differs substantially from φ0, and ‘negative vortice’ are observed, whose penetration leads to the expulsion of magnetic field. Expand
