利用高温高压方法成功地合成出(R0.4Pr0.6)0.5Ca0.5Ba2Cu3O7-δ(其中R=La,Pr,Nd,Sm,Eu,Gd,Y)单相123相超导体.其结果表明,在Pr系的R-123相化合物中掺Ca都能够获得高Tc的超导体,其超导转变温度都在100K左右.

The nearly single phase (R0.4Pr0.6)0.5Ca0.5Ba2Cu3O7-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 Tc above 100K.-
