Simulation of a Vortex Lattice of a Superconductor of the Second Type with Irregularities and Vacancies.

In the framework of the London model, computer modeling has been carried out and the distribution of the magnetic field in a massive superconductor of the II kind has been found, taking into account changes in the inhomogeneity of the magnetic field of an 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 experimental data on the observation of the local magnetic field, the consideration of this circumstance can change the conclusions concerning the type of vortex lattice and the parameters of the superconductor.
