Study of superconducting at Westinghouse

Work at Westinghouse was aimed at determining technically important parameters of newly discovered oxide compounds. The authors did not participate in the race toward new compounds of even higher T's, although early experiments with fluorine substitutions might be construed as an indication to the contrary. Collaboration with Boeing Corporation resulted in a somewhat provocative structural determination which, if it can withstand further tests, might have important implications for understanding of superconductivity. Transport properties and carrier density determinations were of particular interest. As a consequence of joint work with NBS, the combination of J/sub c/ data derived from magnetization and transport measurements, also supported by complex susceptibility results, contributed to the definition of the intergrain connectivity problem. It is intended to continue to investigate this problem in order to determine the feasibility of technically useful conductors operating at higher cryogenic temperatures up to 77K. Recently started film synthesis work will be directed at superconducting electronic applications
