Description

Structural analysis on the cubic skutterudite compound PrOs4Sb12 by single crystal neutron diffraction is presented. There are surge of interests on large-amplitude thermal vibration of a guest ion inside an over-sized cage, called 'rattling', and its relationship with their physical properties. A combination of single crystal neutron diffraction and analysis by maximum-entropy method offers an ability to reveal detailed potential shape and anharmonicity in real space without the need for specific model. A clear picture of rattling in PrOs4Sb12 is successfully revealed. (author)
