Abstract
For a large number of YBa2Cu3O7−δ single crystals which were grown by a flux method in different crucibles the anisotropic resistivity has been measured. An analysis of the metallic in-plane resistivityρ ab gives evidence for different carrier concentrations in the individual samples caused by different amounts of oxygen disorder effects in theab-planes. The temperature dependence of the out-of-plane resistivityσ c which is also metallic for the best samples is determined by the applied crucible material. From the luctuation conductivity in theab-plane aboveT c the coherence length ξ c (0)≃2.5 Å can be determined in good agreement with values obtained fromH c2 measurements.
