Abstract We report the results of thermodynamic measurements in external magnetic field of the cubic Ce-based cage compounds CeT₂Cd₂₀(T= Ni,Pd). Our analysis of the heat-capacity data shows that the Γ₇doublet is the ground state multiplet of the Ce³⁺ions. Consequently, for the Γ₇doublet it can be theoretically shown that the Ruderman–Kittel–Kasuya–Yosida interaction between the localized Ce moments mediated by the conduction electrons, must vanish at temperatures much lower than the energy separating the ground state doublet from the first excited Γ₈quartet. Our findings provide an insight as to why no long range order has been observed in these compounds down to temperatures in the milliKelvin range.
