| Abstract: | The liquid alloys,
LiNa and KPb are strongly phase separating (ps) and compound forming (cf)
alloys respectively and are known to have opposite ordering properties. The
Bhatia-Thornton (BT) static structure factors are important indicators of the
ordering properties and can best be understood in terms of ordering potential
obtained from neutral pseudo atom method. In this paper, it is investigated how
this difference in static structural behaviour could influence the dynamical
property like self and mutual diffusion coefficients as a function of
concentration of the lighter component. The method of Helfand’s linear
trajectory principle has been used in the calculation and this gives results
comparable with recent calculations based on VACF total memory function
formalism. Both the methods yield D
versus 1/T curve almost linear
similar to what is found for pure liquid metals. |
