Metastability and Paramagnetism in Superconducting Mesoscopic Disks
Metastability and Paramagnetism in Superconducting Mesoscopic Disks
A projected order parameter is used to calculate not only local minima of the Ginzburg-Landau energy functional but also saddle points or energy barriers responsible for the metastabilities observed in superconducting mesoscopic disks [A. K. Geim et al., Nature (London) 396, 144 (1998)]. We calculate the local minima magnetization and …
