Effect for Inhomogeneity by Pb Substitution on (Bi1-yPby)2Sr2Ca1-xYxCu2O8+δSingle Crystals

Shingo Komaki, Y. Kourogi, Taiki Murano, Akiko FURUSHIMA et autres

Inhomogeneity is one of the most important problems for the investigation of the superconductor-insulator transition. Y and Pb co-doped Bi2Sr2CaCu2O8+δ(PbY-Bi2212) crystals were fabricated by the self-flax method in order to control both carrier density and dimensionality. The Y-content of PbY-Bi2212 crystals was …
