| 中文摘要 | The nearly single phase (R0.4Pr0.6)(0.5)Ca0.5Ba2Cu3O7-delta compounds (R = La, Pr, Nd, Sm, Eu, Gd and Y) with T-c about 100K were prepared under high pressure and high temperature using the cubic-anvil apparatus. The T-c is much higher than that of the traditional R-123 superconductors without doping Ca on the rare-earth site. For various rare earths with different ionic radii, the (R0.4Pr0.6)(0.5)Ca0.5Ba2Cu3O7-delta compounds have almost the same critical temperature. This is different from the result of the ion-size effect of rare-earth ions in R1-xPrxBa2Cu3O7-delta compounds. Our results show that Pr has the same properties as other rare earths in the 123-phase compounds due to the doping of Ca. |
