    Abstract
  • The critical temperature Tc of the superconductor HgBa2Ca2Cu3O8+y (Hg-1223) sample is determined by four probe resistivity measurements under quasi-hydrostatic pressure up to 7.8 GPa. Tc increases from 130K at ambient pressure to 141 K under a pressure up to 5.4 GPa. dTc/dp=1.85 K/GPa at pressures below 5.4 GPa. The moving of some oxygen atoms and the coupling between CuO2 planes were used to analyzed the pressure effect on Tc of the high Tc superconductors.
