Electrical resistivity of liquid Mg–Al, Na–Cs, Ni–Ce, Li–Cd and Mg–Cd alloys within the‘2kF’ scattering model

Abstract

The resistivities of liquid Mg–Al, Na–Cs, Ni–Ce, Li–Cd and Mg–Cd alloys werecalculated. The Faber–Ziman diffraction model and the Morgan–Howson–Saub‘2kF’ scattering model were used in calculations. The results obtained within these two modelsfor the same alloy and with use of the same set of parameters differ substantially, even foralloys that are not highly resistive. It is possible in principle to achieve good agreementwith experiment by means of each of these two models; however we suggest that the‘2kF’ scattering model is the appropriate method of calculation of the electrical resistivity forliquid alloys because the quantum interference effects should always be taken intoaccount.
