Abstract

Specific heat measurements of YbB 12 have revealed that the band gap is formed on the Kondo lattice originated from the Γ 8 ground state. Increase of C / T of Yb x Lu 1− x B 12 in the low temperature region takes place in the concentration range larger than x ≈ 1 2 and its origin also is from 4f-band gap formation.
