在（100）MgO衬底上进行单目标溅射制备了（Bi, Pb） srccao超导薄膜，并对其进行了适当的退火处理。通过改变退火后的温度和时间，我们可以根据需要得到9k（2201）或80k（2212）的超导相。特别有趣的是，这两个相可以从一个可逆地转变为另一个，正如晶体结构和输运测量所证实的那样。
(Bi, Pb)SrCaCuO superconducting films have been successfully obtained from single-target DC sputtering, deposited on (100) MgO substrate, followed by an appropriate annealing treatment. By varying the post-annealing temperature and time, we can have 9 K (2201) or 80 K (2212) superconducting phase as desired. It is particularly interesting to find that the two phases can be transformed from one to the other reversibly, as confirmed by both crystal structure and transport measurement.
