Phonon dynamics of Zr67Ni33 AND Fe80B20 binary glassy alloys

“…The pseudopotential perturbation theory is an accepted tool for determining properties of amorphous alloys. As far as analytical calculations are concerned, many approximations based on model approaches are available to study the BMGs [1][2][3][4][5][6][7][8][9][10][11]. Shaw's optimized constant-core model pseudopotential [36] along with five different local field correction functions viz.…”

“…However, the well suitable pseudo-alloy-atom (PAA) model explains such interactions vary precisely. Hence, in the present article, the PAA model is used to investigate the phonon dynamics of 100− binary BMG systems [1][2][3][4][5][6][7][8][9][10][11].…”

“…Considering these binary combinations of amorphous alloys to be mono-component fluids, the effective ion-ion interactions are given by [1][2][3][4][5][6][7][8][9][10][11],…”

“…The self-consistent band structure calculation can provide the partials-density of states which can be used to obtain . The characteristics energy wave number term ( ), with as the -space vector, under integration in the above equations, can be written as [1][2][3][4][5][6][7][8][9][10][11],…”

“…Similarly, Lad and Pratap [18] have theoretically investigated the PDC of Zr-Ni BMG with model potential formalism using TG [31,32] and BS [28] approaches and got the results very close to the experimental and theoretical data available in the literature. While, Vora and coworkers [1][2][3][4][5][6][7][8][9][10][11][12] have evaluated the collective dynamics of some BMGs using Ashcroft's empty core model pseudopotential [34] Singh et al [19] have examined Zr-Ni BMG with HB [30], TG [31,32] and BS [28] approaches using a newly constructed free model potential, which is, in fact, the alteration of the Ashcroft's model potential [34] only. The electronic structure, bonding and 3D atomic structure of Zr67Ni33 BMG were studied by Sugita et al [20].…”
