Abstract
High-temperature superconductivity was observed in the system (AlxY1−x)Ba2Cu3O6.5+δ for 0≤x≤0.85. Transition temperatures at zero resistance vary between 90.6 and 50 K, and are related to gradual crystal lattice changes. At x=0.90 a time- and current-dependent resistance is found for T<25 K.
