Optical properties of the filled skutterudites CeT 4 Sb 12 ( T = Fe , Ru , Os )

چکیده
We have measured the optical conductivity s1ðoÞ of the filled skutterudites CeFe4Sb12; CeRu4Sb12; and CeOs4Sb12: These s1ðoÞ spectra are explained in terms of the hybridization between Ce 4f states and conduction ðcÞ electron states. From the comparison of the s1ðoÞ spectra, it is concluded that the degree of c–f hybridization is strongest for CeFe4Sb12 and weakest for CeOs4Sb12: r 2003 Elsevier B.V. All rights reserved.

Strong coupling between 4f valence instability and 3d ferromagnetism in Yb(x)Fe4Sb12 studied by resonant x-ray emission spectroscopy.
We have investigated the temperature and pressure dependency of the electronic structure of Yb-filled skutterudites, YbFe(4)Sb(12) and Yb(0.88)Fe(4)Sb(12), using x-ray absorption and emission spectroscopies. An anomalous increase of the Yb valence, which is beyond the conventional Anderson model picture, is found to coincide with the onset of the ferromagnetic order in the x=0.88 sample below 2...

متن کاملNew correlated electron physics from new materials
Many important advances in the physics of strongly correlated electron systems have been driven by the development of new materials: for instance the filled skutterudites MT4X12 (M 1⁄4 alkali metal, alkaline earth, lanthanide, or actinide; T 1⁄4 Fe, Ru, or Os; X 1⁄4 P, As, or Sb), certain lanthanide and actinide intermetallic compounds such as URu2 xRexSi2 and CeTIn5 (T 1⁄4 Co, Rh, or Ir), and ...

متن کاملOptical properties of MFe4P12 filled skutterudites
Infrared reflectance spectroscopy measurements were made on four members of the MFe4P12 family of filled skutterudites, with M5La, Th, Ce, and U. In progressing from M5La to U the system undergoes a metalinsulator transition. It is shown that, although the filling atom induces such dramatic changes in the transport properties of the system, it has only a small effect on lattice dynamics. We dis...
