| Abstract: | The oxygen stoichiometry in the YBa2Cu3O7−δ high temperature superconductors is studied, using DSC/DTA techniques on samples subjected to different heat and gas treatments.
Characteristic temperature regions of high temperature superconductivity exchange with oxygen in gas phase are identified
and the resulting structural changes are discussed. |
