Description

Temperature programmed desorption (TPD) chromatograms revealed that a small amount of oxygen was desorbed from high-Tc Bi-Pb-Sr-Ca-Cu-O (BPSCCO) in the range from ca.350 to ca. 650 C prior to a steep increase of oxygen desorption. The Tc of BPSCCO was remarkably lowered with a progress of oxygen desorption especially in this temperature range, and returned reversibly to the original level when the desorbed oxygen was recovered. With no corresponding changes in X-ray powder diffraction pattern being detected, the oxygen desorbed below ca.650 C was concluded to have strong relevance to the superconductivity of BPSCCO
