Abstract

Ultrahigh-resolution photoemission spectra of CeRu₄Sb₁₂ reveal crossover behavior into a low carrier state. The density of states (DOS) around the Fermi level (E_F) decreases on lowering temperature and the semimetalliclike DOS is observed at 5.9 K. The temperature dependence of DOS at E_F is explained in terms of the development of the coherence. The smaller hybridization strength between the Ru-d state and the Ce-4f state prevents the hybridization gap from opening in CeRu₄Sb₁₂, which is realized in CeRu₄P₁₂.
