Effective lowest Landau level treatment of demagnetization in superconducting mesoscopic disks
Effective lowest Landau level treatment of demagnetization in superconducting mesoscopic disks
Demagnetization, which is inherently present in the magnetic response of small finite-size superconductors, can be approximately accounted for by an effective \ensuremath{\kappa} within a two-dimensional lowest Landau level approximation of the Ginzburg-Landau functional. We show this by comparing the equilibrium magnetization of superconducting mesoscopic disks obtained from the numerical solution …
