摘要：
The single-layer oxide superconductor Bi2Sr2CuO6-delta offers an opportunity to study the normal-state properties of the cuprate superconductors down to low temperatures, but crystals of this material display a wide range of stoichiometry and properties. We report measurements of the resistivity and Hall coefficient R(H) on crystals whose cation and oxygen stoichiometries have been determined to an accuracy of 1 to 2%. In superconducting samples there is a pronounced maximum in R(H) at 70 K, which we argue to be a characteristic feature of cuprate superconductors in the normal state.
