• studied in [15][16][17]. The vortex–vortex interaction potential, different from the classical one typical in type-II superconductors K0(r/λ) (r is the distance between the vortex centers) [18], is also observed in superconductors characterized by the Ginzburg–Landau parameter . A vortex structure is also
