Fine Structure in Magnetization of Individual Fluxoid States
A. K. Geim, S. V. Dubonos, J. J. Palacios
Each time a vortex enters or exits a small superconductor, a different fluxoid state develops. We have observed splitting and sharp kinks on magnetization curves of such individual…
Metastability and paramagnetism in superconducting mesoscopic disks
J. J. Palacios
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 meta…
Vortex matter in mesoscopic superconductors
J. J. Palacios
Superconducting mesoscopic devices in magnetic fields present novel properties which can only be accounted for by both the quantum confinement of the Cooper pairs and by the intera…
Vortex lattices in strong type-II superconducting two-dimensional strips
J. J. Palacios
We show how to calculate semi-analytically the dense vortex state in strong type-II superconducting nanostructures. For the specific case of a strip, we find vortex lattice solutio…
