The behavior of superconducting Sn and Sn-In microbridges has been studied as a function of physical parameters of the evaporated films. For a proper choice of mean free path and bridge size, a regime of ideal Josephson-junction-like behavior appears just below Tc. The data are in good agreement with recent calculations by Baratoff, Blackburn, and Schwartz.
