... The change in the temperature dependence of the resistance, R ( T ), of ceramic YBa 2 Cu 3 O 7 - x as oxygen is removed from the sample has been studied. The superconducting transition temperature shifts progressively downward in the process. ... The temperature dependence of the resistivity, ( T ), is linear, with a progressively increasing slope, only at T > 400 K. It is suggested that oxygen condenses on Cu-O chains at T 400 K.
