A zero-temperature magnetic-nonmagnetic phase boundary is accessed in CeRh2Si2 by application of pressure and in CeRh2−xRuxSi2 at ambient pressure for x ≈ 1.0. A comparison of specific heat and resistivity measurements in the two cases emphasizes the importance of disorder in producing non-Fermi-liquid-like behavior in these as well as in other Ce-based systems. © 1997 American Physical Society.
