Abstract
Magnetic, specific heat and resistivity measurements lead to assume that in the Ce
5Rh
4 compound the three different Ce local environments induce two kinds of ground states. The atoms in the position I order magnetically
with a Néel temperature of
K and those in position II and III are responsible for a Kondo-like behaviour. The Ce L
X-ray absorption witnesses the presence of a Mixed Valence ground state.
