摘要：
Films of Bi–Pb–Sr–Ca–Cu–O with desired 2201, 2212 and 2223 phases have been successfully prepared by means of DC magnetron sputtering and precise control of the postannealing process. A preliminary temperature-time-transformation (T-T-T) diagram is proposed from the observation. Pb-loss control is found to be crucial to the high-Tc (2223) phase obtained by the postannealing process, a higher PbO content in the films is observed to extend the temperature region of availability of the high-Tc phase and vice versa. © 1990 The Japan Society of Applied Physics.
