摘要：

By systematically changing the oxygen concentration of YBa2Cu3O7-delta single crystals grown in Au-crucibles, we demonstrate that the incorporated Au-impurities have only a minor effect on the maximum in T(c) due to overdoping. On the other hand, we demonstrate that the Au-impurities significantly increase the oxygen mobility in the basal planes of oxygen deficient YBa2Cu3O7-delta single crystals.
