A spin-polarized neutron diffraction study was carried out in a multiferroic antiferromagnetic An introduction of how to study phonon dynamics by inelastic neutron scattering is provided. The process of deducing interatomic force constants from measured phonon dispersion curves and phonon scattering intensity is explained. Using the technique, an example of analysis on a cage compound is described. A concept of phonon-phonon scattering associated with thermal conductivity is also explained.
