Description

We have made inelastic neutron scattering measurements on the doped Kondo insulators Ce(Rh0.8Pd0.2)Sb and (Ce0.7Th0.3)RhSb. Previous bulk property measurements showed non-Fermi liquid (NFL) behaviour for both compositions. In our inelastic neutron scattering data these two compounds also show E/T scaling behaviour in the dynamical spin susceptibility with different exponents, which is considered a characteristic feature of NFL systems. We discuss how these two different exponents might be related to different microscopic mechanisms of the NFL behaviour in the bulk properties as well as the E/T scaling behaviour seen in the dynamical susceptibility
