Abstract
The pressure dependence of the superconducting transition temperature, T-c(P) has been measured up to 8 GPa for (B1-xCx)(Ba1-ySry)(2)Ca2Cu3O z (x = 0.3, y = 0.25; x = 0.35, y = 0.3) and B0.8C0.2(Ba0.75Sr0.25)(2) Ca3Cu4Oz. Large enhancement of T-c under pressure was observed in the BC-1223 system. In nearly optimally doped B0.65C0.35(Ba0.7Sr0.3)(2)Ca2 Cu3Oz, T-c(P) is observed to increase from 119.6 K at ambient pressure to 133.0 K at 8 GPa. The enhancement of T-c under pressure in BC-1234 was observed to be smaller than that in BC-1223. The results were dis cussed compared with those in the Hg-based system.
