Abstract

Inelastic and elastic neutron scattering studies have been carried out on the mixed-valent, gap-forming compound CeRhSb. For comparison neutron diffraction studies have been also carried out on non-magnetic isostructural compound LaRhSb. Neutron diffraction data down to 18 K do not show any change in crystal structure of LaRhSb and CeRhSb. Broad maxima in the anomalous thermal expansion are seen in CeRhSb (relative to LaRhSb) which suggest lattice thermal expansions and contractions, which may be correlated to their magnetic behaviour. No gap-type excitation, as expected for gap-forming Kondo semimetallic compounds, is evident in CeRhSb from the low energy inelastic neutron scattering studies at 2 K. The high energy neutron scattering studies reveal a broad magnetic response centered at 35 meV, consistent with the mixed-valent behaviour of the Ce ions in CeRhSb.
