Low-temperature properties characterize the hexagonal compound CeRu3Si2 as a mixed-valent system intermediate between weakly mixed-valent systems like CeSn3 or CePd3 and strongly mixed-valent systems like CeRu2. The dimensionless ratio of the Pauli susceptibility (χ0≈9.4×10-4 emu/mole) and the linear specific-heat coefficient (γ≈39 mJ/mole K2) is about 0.8. CeRu3Si2 exhibits type-II superconductivity below Tc≈1 K, which is much lower than Tc≈7 K of the La homolog.
