Abstract

The evolution of superconducting transition of CuBa₂Ca₃Cu₄O_10+δ (i.e. Cu-1234) superconductor has been studied by using diamond anvil cell technique. The Tc of Cu-1234 can be enhanced continuously from ambient reaching to 123 K at 15 GPa. This seems the one more system besides Hg-12(n-1)n which demonstrate the positive pressure effect on Tc over a wide pressure range above 10 GPa.
