Resistivity and structural studies on oxygen-deficient single-phase samples of polycrystalline YBa2Cu3O7- are presented. The oxygen content is controlled through annealing in He atmosphere. By analyzing the behavior of the normal-state resistivity as a function of in terms of one-dimensional conduction, we provide evidence that one-dimensional CuO chains are responsible for the dominant normal-state conduction and the superconductivity at 91 K. The effects of oxygen deficiency on the superconducting properties are also discussed. © 1988 The American Physical Society.
