Effect of La Doping on Structural and Superconducting Properties of (Bi, Pb)-2223 Ceramics

Superconducting ceramics with nominal composition Bi1.6Pb0.4Sr2Ca2-yLayCu3O10+d (0 ≤ y ≤ 0.04); were prepared in pellet form by conventional solid-state reaction method. The samples were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), temperature-dependent resistivity measurements,...
