摘要：

We report on the preparation of (Bi-1-xPbx)-Sr-Ca-Cu-O thin films with Tc up to 108K. Lead doping was used to promote the 110 K phase. The highest Tc were obtained for deposits with x~15%-20% after 14h (8000Å thick film) or 11h (3000Å) 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. © 1990.
