Abstract:
In this paper, we investigated a single vortex in a thin superconducting film containing multiple flux quanta. Obtained the exact expression for the free energy of the vortex taking into account the distribution of the order parameter near the core of the vortex. It is shown that the merging of the vortices containing one quantum of flux, in a dense swirl of liquid.
Keywords:vortex liquid, superconducting film, the Abrikosov vortex, the superconductor of the second kind.
