• superconductors have been analyzed. Clustering of the vortex system is demonstrated. The melting of a vortex lattice with increasing temperature has been studied. Keywords: high-temperature superconductor; HTSC; intertype superconductors; Monte Carlo method; vortex lattice; vortex–vortex interaction potential

• the magnetic field penetrates the superconductor in the form of Abrikosov vortices [1]. In high-temperature superconductors (HTSCs), such as Y- and Bi-based cuprates, the vortex lattice is further complicated since these compounds have a layered structure [2][3][4][5][6]. The vortex filament in these

• discovered. Indications were also obtained that the second peak on the magnetization curve (second magnetization peak) at low temperature (less than 0.55Tc) coincides with the transition between the regimes of the flow of the vortex lattice. The measurements were also performed in a magnetic field inclined

• films have been created with thickness modulation properties exhibiting periodicity from 60 to 140 nm, leading to a strong pinning potential for the vortex lattice. This produces local minima in the resistivity up to high magnetic fields (2.2 T) in a broad temperature range due to commensurability

• effects between the pinning potential and the vortex lattice. The results show that the combination of single-step FIBID fabrication of superconducting nanostructures with built-in artificial pinning landscapes and the small intrinsic random pinning potential of this material produces strong periodic

• pinning potentials, maximizing the opportunities for the investigation of fundamental aspects in vortex science under changing external stimuli (e.g., temperature, magnetic field, electrical current).
