Heat treatment under high-pressure oxidizing atmosphere (oxygen partial pressure of 400 atm) is found to lower the T_c of the superconductor YBa₂Cu₃O_y. The powder X-ray diffraction pattern and the oxygen content measurement suggest that the excess oxygen occupies the oxygen defect site between the Ba-Ba layers.
