PROXIMITY EFFECT - AMORPHOUS SN-FE, AMORPHOUS BI-FE FILMS uri icon

abstract

  • We report the results of an experimental investigation of the proximity effect in sandwiches of amorphous Bi-Fe and amorphous Sn-Fe. The measurements on a-Bi films resolve a controversy concerning its coherence length while that derived for a-Sn is consistent with values reported from critical-field measurements. The pair penetration depths determined from a new analysis technique are consistent with values derived from other proximity experiments which employ Fe normal layers. A linear decrease of the transition temperature with resistance per square and inverse film thickness, an apparently universal characteristic of amorphous superconducting films, was also observed in these experiments. 1981 The American Physical Society.
