用FLAPW方法计算了YbFe4Sb12及其参考化合物LaFe4Sb12的电子能带结构.结果表明，Yb离子具有中间价态，但索末菲系数的计算值只有观测值的一半，说明存在强关联电子效应。
The electronic band structures are calculated for YbFe 4 Sb 12 and its reference compound LaFe 4 Sb 12 , by using an FLAPW method. The result reveals that the Yb ions have an intermediate valence but the calculated Sommerfeld coefficient is a half of the observed value indicating the strongly correlated electron effects.
