Body text
Site-specific nuclear resonant inelastic scattering is a unique technique to study Phonon density of states for different sites depending on the chemical state . The technique is applicable to any materials containing Mössbauer nuclei such as 57Fe and 119Sn and provides knowledge about local vibration modes which depend on the chemical state.
Figure. Phonon densities of states of 57Fe in the magnetite sample. The phonon density of states of all Fe is shown in solid circles. The partial phonon densities of states of the A and B sites obtained experimentally are shown as downward and upward triangles, respectively.
