摘      要：The perparation of BPSCCO thin films by DC magnetron sputtering is reported. We prepared high mass density target of Bi2Pb0.6Sr2Ca2Cu3O10. By varying the substrate temperature, ratio of Ar and O2 pressure as well as the distance between target and substrate, we were able to optimize the process for c -axis oriented thin films of Bi-Compounds. As deposited films show Tcon at about 95K. These films were examined using the electron-probe microanalysic (EMPA) and X-ray diffraction (XRD). The results of electrical resistivity and Hall effect have been discussed. Hall voltage in the mixed state is strongly nonlinear, showing certain features that suggests that vortex depinning mechanism plays an important role in the Hall effect behaviour.
