Scaling of the vortex-liquid resistivity and temperature and magnetic field dependent activation energy in Ho doped (Bi, Pb)-2212 superconductor Abstract. The influence of Pb and Cr substitutions on the superconducting properties of Bi 2 Sr 2 CaCu 2 O 8 (Bi-2212) superconductors is reported. The samples were prepared from Bi 2 -xPbxSr2Ca2-yCryCu3O10- (x=0-0.3, y=0-0.3) starting composition by the solid-state-reaction method. XRD analysis showed formation of pure Bi-2212 for (x=0, y=0), (x=0.3, y=0.2) and (x=0.3, y=0.3) starting compositions. Excess conductivity analysis based on Asmalazov-Larkin theory on single-phased Bi2212 samples showed 2D to 3D transition in superconducting fluctuation behavior (SFB) for all the samples. Highest 2D -3D transition temperature, T2D-3D was observed at Pb and Cr substitutions of x=0.3 and y=0.2 respectively.
