- 論文の詳細を見る
One-electron energy band structure for LuInCu., which is a proper referencematerial for the study of the valence transition in YbInCu., is calculated by a self-consistent APW method with the local density approximation. The calculated resultshows that the compound is the semimetal. This property is consistent with the ob-served unusual behavior. In order to estimate the naixing term between the 4 f electronand the valence and conduction electrons, the energy band structure for YbInCu. isalso calculated. The obtained result is followings; (pfo)=O.27 eV for Yb 4f and Cu pstates and (dfo)= -0.l4eV for Lu 4f and Cu 3d states. Thescr values are nearly sameorder as those of Ce compounds.band theory, valence transition, YbInCu., LuInCu.
