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 (intertypesuperconductors) 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.

potential observed in ferromagnetic superconductors. Clustering of vortices was observed in magnetic fields from 400 to 1000 G. For a vortex system interacting with a potential characteristic of intertypesuperconductors, melting inside vortex clusters was observed with increasing temperature. At
