Abstract

The superconducting transition temperatures (Tc) of optimally doped HgBa2Cam-1CumO2m+2+δ with m=1, 2, 3 and (Hg1-xPbx)Ba2Cam-1CumO2m+2+δ were examined under quasihydrostatic pressures up to 45 GPa. There seems to be a universal enhancement of Tc under pressure regardless of m. Highest Tc of 164 K is reached in the 3-layer compound. This enhancement is strongly suppressed by Pb doping.
