Surface currents in fine superconducting filaments

Measurements were made of the magnetic moment observed in a fine filament NbTi superconductor upon cooling through the transition temperature in a magnetic field large compared with H c1 . A partial Meissner effect was observed and this effect is interpreted in terms of surface current, body current...

Description
Summary:Measurements were made of the magnetic moment observed in a fine filament NbTi superconductor upon cooling through the transition temperature in a magnetic field large compared with H c1 . A partial Meissner effect was observed and this effect is interpreted in terms of surface current, body current and the magnetic moment of the flux lines. The interpretation is used to study the surface current behavior.
