Abstract

Inelastic nuclear resonant scattering spectra of ^(57)Fe atoms were measured on Pt_3^(57)Fe and Pd_3^(57)Fe with the L1_2 crystal structure, and with the same crystallographic sites for ^(57)Fe atoms. Phonon partial density of states curves for ^(57)Fe were obtained from these spectra. In comparison to the non-dispersive Einstein-like optical modes in Pt_3^(57)Fe, the optical modes in Pd_3^(57)Fe are broader. This difference can be understood in terms of the difference in mass of Pd and Pt.
