Abstract
Y(Ba1-x-xSrx)2Cu3O7-y (0≤x≤1.0) were prepared. The temperature dependences of resistivity and ac susceptibity were measured. The annealing effect for the ceramics has been investigated. Single phase ceramics are obtained in the range of 0≤x≤0.6. The Tc decreases linearly with increasing x. The Tc scarecely changed regardless of annealing conditions, except quenching from higher temperature than 500°C.
