Abstract
Thin film electrodes particularly suited for Josephson devices of improved thermal cyclability are prepared by depositing thin films of superconductive metal and an intermetallic compound former on a substrate held at a temperature below about 100.degree. K. and at a pressure below about 1.times.10.sup.-7 Torr so that intermetallic compound formation occurs at the grain boundaries of the metal to inhibit grain growth. The thin film electrodes are characterized by median grain size <100 nm.
