Abstract The ac magnetic susceptibility, the magnetoresistance R(H) and the dependence of the resistivity on temperature under different applied field were investigated in the Pb-doped Bi-Ca-Sr- Cu-O system. A superconducting phase with Tc~100K exists in this sintered sample. It forms a well connecting network, and therefore the Josephson coupling between the superconducting grains is sharply improved by doping lead.
