Phonon dispersion in Ni0.55Pd0.45 and Ni0.5Fe0.5 alloys
Abstract
The phonon dispersion in the Ni0.55Pd0.45 and Ni0.5Fe0.5 alloys has been studied within the framework of the transition-metal model-potential approach of Animalu and the mean-crystal model. A short-range three-body interaction has also been incorporated in the study. The theoretically calculated phonon-dispersion curves of these alloys are found to be in good agreement with the experimental data.
