Abstract:
The resistivity of superconducting Pb-doped Bi–Sr–Ca–Cu–O single crystal, with 2212 structure, has been measured using Montgomery technique. The resistivity, like in other high T c oxide superconductors, shows very strong anisotropic characteristic, with a typical metallic behavior but remains a residual resistivity at T = 0 K in the direction parallel to the a − b plane and a "semiconducting-like" temperature dependence in the c direction. The anisotropy (ρ c /ρ ab ) is about 10 4 . But the value of resistivity in a − b plane is larger than that of Bi 2 Sr 2 CaCu 2 O y crystal. This may imply that the Bi–O plane plays an important role in superconductivity in this kind of structure.
