Abstract: High-resolution inelastic x-ray scattering (IXS) was carried out in the filled-skutterudites ROs4Sb12 (R = La, Pr, Nd, Sm). Low-energy rare-earth modes were found in these compounds. They show significant rare-earth dependence, suggesting a correlation with lanthanide contraction. We discuss the relation between the present IXS measurements and reported other experiments.
