Measurements of the temperature-dependent specific heat and thermal expansion coefficient near a T=0 magnetic-nonmagnetic boundary, accessed in CeRh<SUB>2</SUB>Si<SUB>2</SUB> by application of pressure and in CeRh<SUB>2-x</SUB>Ru<SUB>x</SUB>Si<SUB>2</SUB> at ambient pressure by chemical substitution, emphasize the role of disorder in producing non-Fermi-liquid behavior. Interestingly, superconductivity also develops near this boundary in some crystallographically-ordered Ce-based heavy-fermion compounds.
