  • The new bulk superconductors Pr1-xCaxBa2Cu3O7- (0.4x0.6) have been synthesized under a high-pressure of 5 GPa and 1 000 ℃ for 30 min. The solubility of Ca in Pr-123 phase has much increased by the high pressure synthesis method, that effectively compensates the hole-filling by Pr on CuO2 planes and achieves superconducting.
