Evidence for valence fluctuaction in the CeSn3 compound.

Abstract

We present the experimental results of magnetisation, magnetic susceptibility (at normal pressure and under a pressure of 6 kbar), electrical resistivity and thermal expansion, performed on a single sample of CeSn3. These measurements were done over the temperature range of 1-4 < T < 300 K. We used an extensión of the Ramirez-Falicov theory outlined by Alascio et al to show that these and previous specific heat and thermo power results can be related by including a mixing between the to possible Ce configurations.
