Vortex lattices of layered HTSCs at different vortex–vortex interaction potentials

Magnetization reversal processes in a vortex system with different potentials of vortex–vortex interaction were studied using the Monte Carlo method within the framework of a two-dimensional model of a layered high-temperature superconductor. Interaction potentials close to the potential applicable in superconductors with the Ginzburg–Landau parameter κ = 1/2 (intertype superconductors) and in ferromagnetic superconductors have been analyzed. Clustering of the vortex system is demonstrated. The melting of a vortex lattice with increasing temperature has been studied.
