“…Using the Bhatia Thornton formalism [15] the structure of a binary system is described in terms of correlations between density fluctuations and concentration fluctuations, the Fourier transforms of them in $-space being the partial Bhatia Thorn-ton structure factors Sxy(Q), Scc(Q), and S$c(Q)-Here another definition of the total structure factor is convenient:…”

The three partial Faber Ziman structure factors as well as the Bhatia Thornton structure factors of the metallic glass NigiBig were evaluated by neutron diffraction experiments using the isotopic substitution method. In one of the investigated specimens the isotopic composition of the components was adjusted in such a way as to make it possible to measure directly with one diffraction experiment the correlation between the metalloid atoms. From the three partial pair correlation functions the atomic distances and the partial coordination numbers are determined. The results demonstrate the strong chemical ordering in amorphous NisiBig. Particularly the distance correlation between the boron atoms turned out to be very pronounced.The experimental results agree with the main features of a geometrical packing model of soft spheres.

“…As they pointed out (Bhatia & Thornton, 1970), the fluctuation of the particle number ((AN)2)/.N and the correlation term ((Ac,)(AN)) are expressed by the concentration fluctuation N'((Ac,)2), partial molar volumes of the components (v,, and vt~ ), and isothermal compressibility Kr. Therefore we can obtain three kinds of fluctuations of the sample separately by the zero-limit scattering, if we have the thermodynamic data (v,, v~ and Kr).…”

“…At some stage, use will be made of the Bhatia-Thornton (BT) concentration-concentration, S CC ( q, ω) and number-number, S NN ( q, ω) partial dynamic structure factors [24], which are linear combinations, weighted by the concentrations, of the AL ones. Another important dynamical magnitude is the i-type component particle current…”

We report an ab-initio molecular dynamics study on the collective excitations in several s-p bonded liquid binary alloys. Results are reported for the Li-Na, Li-Mg, K-Cs and Li-Ba liquid alloys at different concentrations, which display mass ratios ranging from ≈ 3 for Li-Na to ≈ 20 for Li-Ba, and varying ordering tendencies, ranging from strong homocoordinating in Li-Na to mildly heterocoordinating for one concentration of Li-Ba. The study has been carried out using the orbital free ab-initio molecular dynamics method, combined with local ionic pseudopotentials constructed within the same framework. We analyze the dependence of the collective modes on the concentration and the mass ratio of the alloy, finding a common behaviour for all systems notwithstanding the different ordering tendencies.
