Softening of Phonon by Filled Rare-Earth Ion Motion Common to Skutterudite with Sb Cages

We investigate phonon modes of the rare-earth filled skutterudite compounds CeRu ... Sb ... , CeOs ... Sb ... , PrRu ... Sb ... , and PrOs ... Sb ... by using an inelastic neutron scattering technique. These materials exhibit similar low-lying motions of filled ions inside the Sb cages that softens...
