Abstract
In the present study, we report the vibrational dynamics of Pd39Ni10Cu30P21 bulk metallic glass in terms of the phonon Eigen frequencies of the localized collective excitations using Show’s optimized model pseudopotential at room temperature. While theoretical effective atom model (EAM) with Wills-Harrison (WH) approach are used for the computation of the interatomic pair potential (PP) and pair correlation function (PCF). The phonon dispersion curves are computed through Hubbard-Beeby (HB) approach. Various elastic and thermodynamic properties have been reported from the elastic limit of the phonon dispersion curves. The screening dependency on the aforesaid properties is studied by adopting different kinds of local field correction functions
