The onset temperature (T_c) of the Meissner signal for HgBa₂Ca₂Cu₃O_y (which is 134 K under normal pressure) has been measured under high pressure up to 11 Gpa. It is observed that T_c increases with increasing pressure at the rate of dT_c/dP = 2. 0. K/ GPa and then dT_c/dP becomes relatively small above 6 GPa. The maximum of T_c observed in this experiment is as high as 150 K at 11 GPa. This value is higher than those reported for any high-temperature superconductors.
