Different evolution of the intrinsic gap in strongly correlated SmB6 in contrast to YbB12

Dependence of the spectral functions near the Fermi level on temperature and rare-earth atom doping was studied in detail for strongly correlated alloys Sm _1− _x Eu _x B _6 and Yb _1− _x Lu _x B _12 by photoelectron spectroscopy at ∼8000 eV as well as at 7 and 8.4 eV. It was found that the 4f latti...
