To investigate the mixed valence state, the magnetic susceptibility X (T) of CeRu3 Si-2 has been measured. The temperature dependence of, X (T)TIC in several mixed valence Ce and Yb compounds is plotted against temperature, where C is the Curie constant of Ce3+ or Yb3+ ion. The spin fluctuation temperature T-sf has been estimated. The scaling of chi(T)TIC vs. T/T-sf is found good in both Ce and Yb compounds. CeRu3Si2 is found to be a typical mixed valence system. The difference in the low-temperature susceptibility chi (0), electronic specific heat coefficient gamma and superconducting transition temperature T-s among Ce and Yb mixed valence compounds are discussed in terms of T-sf and Wilson ratio R-w.
