✦ Synopsis

Parent Bi2CaSr2Cu2Os+6 superconductor was doped with oxygen by annealing powder sample at 500 °C in the flowing oxygen atmosphere with intermittent grinding. The amount of amorphous phase and insulating layer found on the sanh~le surface was increased with more oxygen doping.

As a consequence, the sharpness and intensity of the XRD peaks were reduced, and the room temperature conductivity, Tc, as well as the magnetic susceptibility were decreased.

The formation of the Cu-Bi2CaSr2Cu208 interface has been studied by photoelectron spectroscopy using synchrotron radiation. Photon energies in the range 20-1000 eV were utilized in order to probe both the valence band and to monitor chemical changes upon Cu deposition, as revealed by the corelevel s
