B(P)SCCO films were prepared on MgO substrate by a double cathode dc sputtering with a mosaic BiχSrCaCuyOz and (Bi0.7Pb0.3)χ SrCaCuyOz target. The films were deposited at 200 and 550, and then annealed. We have obtained the B(P)SCCO films with Tc of 90-100 K under the condition of the deposition at 550 and the in-situ annealing in 200 Torr O2 and the post-deposition annealing at 860.
