From: First Principles Theory of the hcp-fcc Phase Transition in Cobalt
In the top-left panel the phonon dispersion relation along high symmetry lines for FM hcp Co is shown. The experimental values (dots) are taken from ref. 14. The calculated hcp phonon DOS is shown to the right of the figure. In the bottom-left panel the phonon dispersion relation along some high symmetry lines for FM fcc Co is displayed. The experimental values were obtained for Co0.92Fe0.08 (dots) in ref. 15. The fcc phonon DOS and the calculated DOS obtained from the phonon spectra15 (dashed-line) for fcc Co0.92Fe0.08 are presented to the right of the figure.
