Description
The nearly single phase (R0.4Pr0.6)0.5Ca0.5Ba2Cu3O7-δ (R = La, Pr, Nd, Sm, Eu, Gd and Y) superconducting compounds should be prepared at high temperature and high pressure. The critical temperature of these compounds is over 100 K which is much higher than that of the traditional R-123 superconductors which do not have Ca doping on the rare-earth site. Our results shows that Pr behaves in the same way as other rare-earths in the 123-phase compounds due to the doping with Ca ions
