Pseudopotential in the study of phonon dynamics of Pd-based metallic glasses

Phonon Dispersion in Amorphous Ni-Alloys

“…In the present study, for TM-LA, TM-TM, and TM-M metallic glasses, the pair potential is computed using [6] …”

“…Here Z s ≈ 1.5 is found by integrating the partial s-density of states resulting from self-consistent band structure calculation for the entire 3d and 4d series [6], while Ω 0 is the effective atomic volume of the one component fluid. The energy wave number characteristics appearing in Eq.…”

“…The expressions for longitudinal phonon frequency ω L and transverse phonon frequency ω T per HB approach are [3,[6][7][8]:…”

“…the longitudinal ω L and transverse ω T phonon frequencies are proportional to the wave vectors and obey the relationships [6][7][8] …”

“…And only recently there has been an explosion of interest to these studies as more promising materials are produced in the amorphous form. The range of applications of metallic glasses is vast and extends from the common window glass to high capacity storage media for digital devices [1][2][3][4][5][6][7][8].…”
