摘要
高温高压下合成出了新块材超导体Ｐｒ１－ｘＣａｘＢａ２Ｃｕ３Ｏ７－δ（０４≤ｘ≤０６），高压合成使Ｃａ在Ｐｒ１２３相中的溶解度有很大提高，从而有效地补偿了Ｐｒ对ＣｕＯ２面空穴的填充而使样品超导。
The new bulk superconductors Pr 1- x Ca x Ba 2Cu 3O 7- δ (0 4≤ x ≤0 6)have been synthesized under a high pressure of 5 GPa and 1000℃ for 30min.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 CuO 2 planes and achieves superconducting.
