A polycrystalline phase of Hf-filled CoSb3 skutterudite was successfully prepared by the mechanical alloying technique followed by the spark plasma sintering process. X-ray diffraction and scanning electron microscopy linked with energy-dispersive x-ray spectroscopy were used to investigate the result filling the void spaces with Hf. HfCo4Sb12 skut...
The filled-skutterudite compound CeRu4Sb12 shows a pseudogap structure for the optical conductivity spectra similar to the Kondo insulators; however, it exhibits metallic behavior below 80 K. The resistivity shows a large peak at 80 K, and the Seebeck coefficient is positive and also shows a large peak at nearly the same temperature. In order to ex...
