  • Abstract
    We report on sample preparation and electron microprobe analysis in the series Ce1-pYbpFe4Sb12 that shows that a solid solution exists for all compositions in the series. As shown from X-ray absorption spectroscopy, Ce is trivalent throughout the series, whereas Yb valence linearly changes from 2.16 for Yb0.93Fe4Sb12.08 to 2.71 for Ce0.85Yb0.05Fe4Sb12.06. The Seebeck coefficient is enhanced by more than 20% at room temperature in Ce-Yb mixed compounds as compared to CeFe4Sb12 or YbFe4Sb12.
