Structural and electrical properties of cerium doped Bi(Pb)-2212 phases
In this work, a comparative study on the effect of doping by low content cerium at Ca site of Bi(Pb)-2212 phases is presented. Superconducting ceramics of nominal compositions Bi2Sr2Ca1-xCexCu2O8+delta (called CC series) ...
Effect of Yttrium Doping on Magneto-transport Properties of Bi(Pb)-2212 Superconductors
An analysis of the temperature dependence of resistivity results under magnetic fields (0-7 T) is presented for yttrium doped Bi1.6Pb0.4Sr2Ca1-x Y (x) Cu2O8+delta and Bi1.6Pb0.4Sr2-x Y (x) CaCu2O8+delta (x=0 and 0.075) ...
