Growth of the 110 K superconducting phase and characterization of Pb-doped Bi-Sr-Ca-Cu-O thin films prepared by sputtering

Résumé

We report on the preparation of (Bi1-xPbx)-Sr-Ca-Cu-O thin films with Tc up to 108K. Lead doping was used to promote the 110 K phaose. The highest Tc we ~e obtained for deposits with x"'15% -20% after 14h (8000A thick film) or 11 h (3000A) annealing at 855°C-860°C. X-ray diffraction studies and SEM examinations show that films of the 2223 phase are highly c-axis oriented like films of the 2212 phase.
