摘要：
The effect of F doping in the (Bi, Pb)-Sr-Ca-Cu-O system has been investigated by resistance and AC susceptibility measurements. The influence of fluorine on the forming process of superconducting phases and the superconducting properties are shown, and the role of fluorine in the Bi system superconductors is discussed. The effect of the heat treatment of the F doped samples has also been studied. The results indicate that F doping promotes the forming of 2223 phase and increases the bulk T-c.
