Abstract

The superconducting transition temperatures (T_c) of optimally doped HgBa₂Ca_m-1Cu_mO_2m+2+δ with m=1, 2, 3 and (Hg_1-xPb_x)Ba₂Ca_m-1Cu_mO_2m+2+δ were examined under quasihydrostatic pressures up to 45 GPa. There seems to be a universal enhancement of T_c under pressure regardless of m. Highest T_c of 164 K is reached in the 3-layer compound. This enhancement is strongly suppressed by Pb doping.
