Abstract

We have made inelastic neutron scattering studies of Ce(Rh_0.8Pd_0.2)Sb, which is located at the crossover from non-magnetic to magnetically ordered states (i.e. close to a quantum critical point). In the imaginary part of the dynamic susceptibility, we have found clear evidence of E/T scaling behaviour. This E/T scaling behaviour appears to break down at high temperatures and energies. The transition from non-Fermi liquid to localized behaviour in Ce(Rh_0.8Pd_0.2)Sb on an energy scale above ∼15 meV is demonstrated by the observation of both crystal-field and spin-orbit excitations of the Ce³⁺ ions.
