Structural, electrical, and magnetic properties of the co-substituted bi-2212 system textured by laser floating zone technique

In this work, Bi2Sr2CaCu2-x Co x O y (x=0.0, 0.05, 0.10, and 0.25) textured superconductors were prepared by a LFZ melting technique. In all cases, the powder X-ray diffraction patterns of samples show that the Bi-2212 phase is the major one. All samples have good oriented structure, which is a typi...
