High temperature superconductors with a Tc above 40 K have been found to bestrongly correlated electron systems and to have a layered structure. Guided bythese rules, Kamihara et al. discovered a Tc up to 26 K in the layeredLa(O1-xFx)FeAs. By replacing La with tri-valence rare-earth elements RE ofsmaller ionic radii, Tc has subsequently been raised to 41-52 K. Manytheoretical models have been proposed emphasizing the important magnetic originof superconductivity in this compound system and a possible furtherTc-enhancement in RE(O1-xFx)FeAs by compression. This later prediction appearsto be supported by the pressure-induced Tc-increase in La(O0.89F0.11)FeAsobserved. Here we show that, in contrast to previous expectations, pressure caneither suppress or enhance Tc, depending on the doping level, suggesting that aTc exceeding 50's K may be found only in the yet-to-be discovered compoundsystems related to but different from R(O1-xFx)FeAs and that the Tc ofLa(O1-xFx)FeAs and Sm(O1-xFx)FeAs may be further raised to 50's K.
