Abstract

A number of ceramic compounds including YBa2Cu3O7 have been reported to superconduct at temperatures in excess of 35K [1–9]. A critical feature in the processing of these compounds that is required to obtain good superconductive properties appears to be a final annealing stage in an oxygen containing atmosphere to increase the oxygen content of the materials [10]. Without the oxygen anneal step, the superconducting transition temperature drops and the drop in the temperature versus resistance curve becomes less defined.
