Contribution
The study introduces a new analysis of vortex–vortex interactions in layered superconductors using specific interaction potentials.
Findings
Vortex systems exhibit clustering behavior under specific interaction potentials.
Melting of vortex lattices occurs with increasing temperature.
Interaction potentials similar to κ = 1/2 and ferromagnetic superconductors were analyzed.
Abstract
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.
