Abstract

A comparison of the Sr solubility limits in bulk YBa2Cu3O7 and thin film YBa2Cu3O7 has been made. Whereas for the former, single phase samples of YBa2-xSrxCu3O7 are only formed for 0≤x≤1.0 the thin films show a higher solubility range, 0≤x≤1.6. Both the c parameter and Tc decrease with increasing x, and the Sr content of the films has been confirmed by EDAX. These results demonstrate the potential of laser ablation for the synthesis of new and modified oxide superconductors.
