THE LINEAR TEMPERATURE BEHAVIOR OF RESISTMTY AND OXYGEN STOICHIOMETRY IN YBa2Cu3O7-x
-
Abstract
By employing a gettered annealing technique, we studied the relationship between the resistivity ρ(x, T) (20°C≤ T≤ 30°C) and oxygen content in the high-Tc superconductor YBa2Cu3O7-x. ρ(x, T) is approximately linear for 0.0≤ x ≤0.6, and both the slope dρ/dT and the residual resistivity increase continuously decreasing oxygen content. A qualitative analysis is given.
