Molecular dynamics simulations are performed to study the [100] and [111]orientations of the crystal-melt interface between an ordered two-componenthard sphere with a NaCl structure and its coexisting binary hard-sphere fluid.The diameter ratio of the two types of hard spheres making up the mixture istaken to be 0.414. This work complements our earlier interface simulations [J.Chem. Phys.116, 3410] for the same diameter ratio at lower pressures where thesmaller component is immiscible in the solid and the fluid mixture coexistswith a pure FCC crystal of large particles. Density profiles and diffusioncoefficient profiles are presented for the AB interfacial system. We find thatfor this system, the transition from crystal-like to fluid-like behavior ofboth the density and diffusion constant profiles occurs over a narrower regionthan that seen in our previous studies [J. Chem. Phys. 116, 3410] of theFCC/binary fluid system. But similar to what was found in the FCC/binary fluidinterface the transition region for the large particle diffusion constant isshifted about the size of the large particles toward the fluid phase relativeto that for the small particles.Comment: 8 page
