摘要：

Superconducting Tl1-deltaCaBa2Cu2O7 can be prepared without impurity from the corresponding two Tl-O layer cuprate only when some Tl deficiency is incorporated. The Tl1-deltaCaBa2Cu2O7 and Tl1-deltaY1-xCaxBa2Cu2O7 series show maximum T(c) at an optimal hole concentration. The T(c) maximum occurs at a Cu-O distance of ca. 1.924 angstrom.
