Abstract : Thin films of the high-Tc superconductor Bi-Sr-Ca-Cu-0 were prepared by sputter deposition. The films were deposited at room temperature and then post deposition annealed. A microwave measurement system based on a microstrip resonator was established. X-ray diffraction revealed that the films were multi- phase. Resistance of these films did not show a transition when cooled to liquid nitrogen temperatures. Superconductors, Sputtering, Thin films.
