Abstract
Following the observation that the specific heat of Ce0.7Th0.3RhSb shows non-Fermi liquid behavior, we have investigated the inelastic neutron scattering from this compound over the temperature range 10–100K, using the HET spectrometer at ISIS. We have found that the spectral function of Ce0.7Th0.3RhSb displays a power law dependence of energy, i.e. S(ω)∼ω−α, with α=0.33. The dynamical susceptibility obtained from the inelastic scattering spectra displays E/T scaling behavior as in other compounds showing non-Fermi liquid behavior. With increasing energy transfer above 10meV, Ce0.7Th0.3RhSb shows a more localized behavior with two broad crystalline electric field transitions around 20 and 30meV.
