Molecular dynamics study of the static structure of liquid Na-K alloys

Liquid Na-K alloys are studied by molecular dynamics simulations. The interatomic interactions are described from Fiolhais' pseudo potential. The evolution with the composition of the static structure, as well as the isothermal compressibility and the self- and inter-diffusion properties is discussed. Deviation from the behaviour of an ideal mixture is observed and small homocoordination tendencies are highlighted.
