Rare-earth filled skutterudites exhibit a large variety of topical magnetic and electrical properties. Novel skutterudites (body-centered cubic, Im-3, structure) with chemical formula RPt4Ge12 have been synthesized. Detailedmacroscopic measurements performed on the CePt4Ge12 let suppose that this compound is at the border between an intermediate valence (IV) and a Kondo lattice behavior. Its magnetic susceptibility shows a wide bump around 75-80 K, as typically observed in IV systems. The value of the Kadowaki and Woods ratio is closer to what is expected for transition metals, than what is expected for heavy-fermion systems. This makes the case of CePt4Ge12 very intriguing. In order to discriminate between IV or Kondo lattice behavior in CePt4Ge12, we use the inelastic and quasielastic neutron scattering techniques.
