Metastable states of superconducting indium films. II

Abstract

Supercooling fields of In films condensed at 295 and 77 K ha ve been studied. Each series of films defines a different bulk material, whose Ginzburg-Landau (GL) parameter can be obtained from the measured supercooling fields. These bulk metals satisfy the Gor' kov-Goodman relation between the GL parameter and resistivity. Furthermore, this relation is also satisfied by GL parameters of individual type Il films condensed at 77K, while other layers condensed at 295K show deviations ascribed to nonlocal effects. The importance of a careful study of transport properties of the films for a correct interpretation of experiments is stressed.
