Superconductive and Magnetic Properties of Bi2Sr2Ca2Cu3O10+δ Ceramics Doped by Pb

Among the superconducting phases of bismuth-based Bi–Sr–Ca–Cu–O, compound Bi2Sr2Ca2Cu3O10+δ (Bi-2223) is the most interesting because of its relatively high critical temperature (T C =95–110 K) and numerous applications. However, this phase is also known for its low stability and the difficulty of purifying parasites phases including the Bi-2212. To this end, the Pb used in relatively high proportions can stabilize, purify, and improve the further enhancement of T C . The influence of Pb on structural, superconducting and magnetic properties has been extensively investigated in polycrystalline Bi2−x Pb x Sr2Ca2Cu3O10+δ ceramics (0
