Fabrication of (Bi,Pb)2Sr2Ca2Cu3Ox Thin Films

本研究试图制备单相Bi，Pb-2223高温超导体薄膜，以了解其潜力。我们在STO(100)衬底上制备了不含铅的Bi2223薄膜，然后在840oC下用Bi2223小球进行了100h的退火以引入铅。最后，在氧气气氛中进行了后退火处理。我们已经成功地制备了Jc=0.9x106A/cm2(77K，自磁场)的薄膜。此外，首次在薄膜中模拟了Bi2212+CaCuPbO→Bi2223的反应过程。

This research has tried to produce thin films of single phase Bi,Pb-2223 high Tc superconductor in order to understand its potential. We fabricated the Bi-2223 thin films (not containing Pb) on STO(100) substrates, subsequently carried out annealing with Bi,Pb-2223 pellets at 840oC for 100 hours to introduce Pb. Finally, we carried out post annealing in oxygen following atmosphere. We have succeeded in fabricating a thin film with Jc=0.9x106 A/cm2 (77 K, self-magnetic field). Furthermore, it was possible to simulate for the first time in thin films for the reaction process of Bi2212 + CaCuPbO → Bi2223.
