摘要：
We report on a search for intermediate valence and heavy fermion behavior in filled skutterudite compounds. The compound YbFe(4)Sb(12) was synthesized and to our knowledge, is the first example of a filled skutterudite of a heavy lanthanide. Transport, magnetic, and thermal measurements on CeFe(4)Sb(12) and YbFe(4)Sb(12) indicate that these materials have a moderately heavy fermion ground state. (C) 1999 Elsevier Science B.V.
