| Abstract: | The vibrational dynamics of some Zr-based bulkmetallic glasses were studied at room temperature in terms of phonon eigen frequencies
of longitudinal and transverse modes employing three different approaches proposed by Hubbard-Beeby (HB), Takeno-Goda (TG)
and Bhatia-Singh (BS). The well recognized model potential is employed successfully to explain electron-ion interaction in
the metallic glass. The present findings of phonon dispersion curve are found to be in fair agreement with available theoretical
as well as experimental data. The thermodynamic properties obtained by the HB and TG approaches are found to be much lower
than those obtained by the BS approach. |
