We have analyzed the phase transitions in a square lattice of vortices using the thermodynamic approach. For a square array of the artificially created pin centers in superconducting film we have calculated the phase diagram, which reveals the re-entrant melting features. We explain this effect by the nonmonotonic temperature dependence of the vortex-vortex interaction potential.
