Superconductivity in a mixed-valent system: CeRu/sub 3/Si/sub 2/
Journal Article

· Phys. Rev. B: Condens. Matter; (United States)
Low-temperature properties characterize the hexagonal compound CeRu/sub 3/Si/sub 2/ as a mixed-valent system intermediate between weakly mixed-valent systems like CeSn/sub 3/ or CePd/sub 3/ and strongly mixed-valent systems like CeRu/sub 2/. The dimensionless ratio of the Pauli susceptibility (chi/sub 0/approx. =9.4 x 10/sup -4/ emu/mole) and the linear specific-heat coefficient (..gamma..approx. =39 mJ/mole K/sup 2/) is about 0.8. CeRu/sub 3/Si/sub 2/ exhibits type-II superconductivity below T/sub c/approx. =1 K, which is much lower than T/sub c/approx. =7 K of the La homolog.
