【 摘 要 】

The effect of pressure on the copper and praseodymium magnetic order in the system Nd1-xPrxBa2Cu3O7-delta with x = 0.3, 0.5, 0.7, and 1 was investigated by means of the muon spin rotation technique. It was found that the effect of pressure on the Neel temperatures of both copper and praseodymium is positive for the whole range of Pr concentrations (0.3 < x < 1) studied. These findings are in contrast with a number of previous reports and clarify some of the puzzles related to the effect of pressure on superconductivity and magnetism in the praseodymium-substituted R1-xPrxBa2Cu3O7-delta systems, where R is a rare-earth element.
