“…Hartree function does not involve any kind of exchange and correlation effects. While, other four functions are satisfied compressibility sum rule and they have been used earlier by many researchers to analyse various physical, electrical and magnetic properties of liquid metals and their alloys [3][4][5][6]. The parameters of the model potential for pure Ni and Cr have been determined using q = q 0 condition.…”

“…Very recently, we carefully computed the electrical resistivity and thermal conductivity of liquid Ni-Cr at 1400K [5]. We have also reported that electrical transport properties using the nearly free electron theory developed by Faber and Ziman formalism, along with a well established potential model [3][4][5]. As, it is known that Ni-Cr transition metal (TM-alloy) alloys based on iron -subgroup metal take up a special interest in modern technology [6].…”

Abstract. Electrical transport properties viz. electrical resistivity and thermal conductivity of Ni-Cr binary alloys are determined by our recognized single parametric potential model in a wide range of Cr concentration. In this work, screening functions of Ichimaru and Utsumi, Farid et al. and Sarkar et al. are employed along with the Hartree and Taylor functions to study the relative influence of the exchange and correlation effect. The Ni-Cr liquid alloys are studied as a function of their composition at three different temperatures (T=800K, 1000K, 1200K). The present finding of electrical resistivity agrees within 2-12% with experimental findings when the H dielectric function is employed.

Given liquid alloys are studied as a function of their composition at three different temperatures according to Faber-Ziman model. Computed values of electrical transport properties are in good agreement with the experimental data available in literature.

The theoretical study of dynamical variables: velocity autocorrelation function (VACF), power spectrum (PS) and mean square displacement (MSD) of Bi50Zn50 bulk metallic glass at T= 793K, 873K, 1023K and 1123K have been calculated based on the static harmonic well approximation. The effective interatomic potential for bulk metallic glass is computed using our established model potential with the exchange correlation functions due to Farid et al. It is observed that negative dip in velocity auto correlation function decreases as the temperature increases. In the power spectrum as temperature increases, the peak of power spectrum shifts toward lower ω. The obtained result of MSD concludes that the vibrating component in the atomic motion is decreases as increases the temperatures.
