Abstract
The new phase Ce16Ru9 (R $($) over bar$$ 3m, a=13.645 Angstrom and c=2 2.742 Angstrom) was examined via the temperature dependences of the la ttice parameters (10-300 K), magnetic susceptibility (1.5-300 K) and e lectrical resistivity (0.3-300 K). Different Ce valences (+4 and +3) f or different crystallographic sites are proposed from magnetic data an d are supported by previous structural results. No magnetic order is o bserved down to 0.3 K. Highly anisotropic stresses observed in the ele ctrical resistivity temperature dependence are attributed to the anoma lous thermal behaviour of the lattice parameter c.
