The Simulation of a Vortex Lattice in a Nanofilm of a Type-II Superconductor

In the framework of the London model, a computer simulation has been performed and the magnetic field distribution in a thin film of type II superconductor has been found, taking into account changes in the magnetic field inhomogeneity of the irregular vortex lattice. It is shown that the line shape changes significantly depending on the vortex lattice irregularity. This change should be taken into account when interpreting the experimental data on the observation of the local magnetic field; consideration of this circumstance can change the conclusions regarding the type of vortex lattice and the parameters of the superconductor.
