Phonon dispersion in Cr70Fe30 measured by neutron inelastic scattering

Abstract The phonon dispersion relation for the substitutional alloy Cr 70 Fe 30 has been measured using neutron inelastic scattering and the results have been fitted to a 6 neighbour Born-von Karman (longitudinal and transverse springs) model. A calculated phonon density of states is presented. No evidence was found for a strong magnetic influence on the phonon energies.
