A zero-temperature magnetic-to-nonmagnetic transition has been investigated in the heavy-fermion ferromagnet CeRu 2Ge2 from electrical-resistance measurements at pressures up to 15 GPa and temperatures down to 60 mK. We found that the magnetic-to-nonmagnetic phase boundary exists at around Pc;10 GPa. The resistivity shows the quadratic temperature variation expected for the conventional Fermi liquid at low temperatures near Pc . In the present pressure range, neither the metamagnetic nor the superconducting transition was observed at least down to 60 mK. @S0163-1829 ~98!01210-7#
