Abstract :
Superconducting BiSrCaCuO thin films with zero resistivity at 80 K have been prepared by a multilayer deposition and diffusion method. The nominal composition is BiSrCaCu2Oy. X-ray diffraction shows that the same lattice structure as for the bulk material but with strong preferred orientation in the film. The superconductivity of this kind of film is sensitive to treatment temperature but not sensitive to annealing atmosphere. Critical parameters have been measured and compared with the similar YBaCuO thin films
