Inelastic neutron scattering and muon spin relaxation investigations of the deuterated Kondo lattices CeNiSnD${}_x$

X. Y. Zheng, D. T. Adroja, B. Chevalier +4

CeNiSn is a Kondo semimetal where a gap opens at low temperatures due to hybridization between 4$f$ and conduction electrons, but a full insulating state fails to develop. Upon the…
