Surface current and hysteresis in fine filament NbTi superconductors

Measurements of the hysteresis loops, the magnetic moments obtained by cooling in a constant field, and the critical current density of submicron NbTi filaments are consistent with the assumption that surface current is the principal mechanism of current flow in these filaments.
