Studies on structural and superconducting properties of Pb free and Pb doped rare earth (RE) modified Bi2Sr2CaCu2Oy, superconductor show that there is a substantial improvement in the superconducting properties of the Pb and RE co-doped system compared to Pb alone and RE alone doped systems. The improved superconducting properties of the co-doped system are attributed to the combined effect of Pb and RE in reducing the anisotropy, inhomogeneity and porosity and improving the electrical conductivity.
