Evidence for valence fluctuation in the CeSn3 compound

Abstract

Presents 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<300K. The author used an extension of the Ramirez-Falicov theory outlined by Alascio et al. (1972, 1973) to show that these and previous specific heat and thermopower results can be related by including a mixing between the two possible Ce configurations.
