Fermi-liquid scaling in the paramagnetic spectral response of the compoundsCeSn3−xInx

The low-temperature paramagnetic spectra of the compounds $\mathrm{Ce}{\mathrm{Sn}}_{3-x}{\mathrm{In}}_x$ ($0<x<\mathrm{}1\mathrm{}$) show broad inelastic peaks at energies ${\omega }_i$ which scale with $T_{max}$, the temperature of the maxima in the bulk susceptibility, and with $\chi (T\to 0)$ and $\gamma (=\frac{C}{T})$, in quantitative agreement with Fermi-liquid relations. The spectra are well described by an analytic function ${\chi }^{\prime \prime }\left(\omega \right)$ for the degenerate Anderson model. Fits to the data suggest that, if $n_f\simeq 1$, the ground-state degeneracy of Ce is close to $6\mathrm{}(=2J+1\mathrm{})\mathrm{}$.
