【Abstract】 The nearly single phase (R 0.4 Pr 0.6 ) 0.5 Ca 0.5 Ba 2Cu 3O 7-δ superconductors (R=La, Pr, Nd, Sm, Eu, Gd, Y) were prepared under high temperature and high pressure using the cubic anvil apparatus. The measured result shows that we can get superconductivity in all these Ca doping compounds with T c above 100K.更多还原
