Magnetization signature of topological surface states in a non-symmorphic superconductor
Wenjun Kuang, Guillermo Lopez-Polin, Hyungjun Lee +10
Superconductors with nontrivial band structure topology represent a class of materials with unconventional and potentially useful properties. Recent years have seen much success in…
Multiple flux jumps and irreversible behavior of thin Al superconducting rings
D. Y. Vodolazov, F. M. Peeters, S. V. Dubonos +1
An experimental and theoretical investigation was made of flux jumps and irreversible magnetization curves of mesoscopic Al superconducting rings. In the small magnetic field regio…
Non-Quantized Penetration of Magnetic Field in the Vortex State of Superconductors
A. K. Geim, S. V. Dubonos, I. V. Grigorieva +3
As first pointed out by Bardeen and Ginzburg in the early sixties, the amount of magnetic flux carried by vortices depends on their distance to the sample edge and can be smaller t…
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…
Magnetization of mesoscopic superconducting discs
P. Singha Deo, V. A. Schweigert, F. M. Peeters +1
Solutions of Ginzburg-Landau eqns. coupled with three dimensional Maxwell eqns. reveal intriguing magnetic response of small superconducting particles, qualitatively different from…
