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

متن کاملMicroscopic Aspects of Multipole Properties of Filled Skutterudites
We discuss low-temperature multipole states of Nd-based filled skutterudites by analyzing a multiorbital Anderson model with the use of a numerical renormalization group method. In order to determine the multipole state, we take a procedure to maximize the multipole susceptibility matrix. Then, it is found that the dominant multipole state is characterized by the mixture of 4u magnetic and 5u o...
