Magnetic Field Dependence of the Proximity Effect in the Sn/Pb System
The proximity effect in a thin film of tin (N) evaporated onto a bulk lead (S) substrate was studied both in zero magnetic field and with a magnetic field applied parallel to the surface of N Small quantities of indium were added to the tin to shorten its mean free path, but the lead was in the clean limit as far as its superconducting properties were concerned. Measurements were made both above and below the transition temperature (3.62°K) of N The results for zero magnetic field formed the major part of the study and will be reported elsewhere. In this paper we confine ourselves to the magnetic field dependence of the proximity effect.
