Abstract

Ultrahigh-resolution photoemission spectra of CeRu4Sb12 reveal crossover behavior into a low carrier state. The density of states (DOS) around the Fermi level (EF) decreases on lowering temperature and the semimetalliclike DOS is observed at 5.9 K. The temperature dependence of DOS at EF 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.
