Abstract

Molecular dynamics simulations of glassy Ni81B19,starting with a configuration obtained by the Reverse Monte Carlo Method,indicate a calorimetrie glass transition at 960 K and point to a significantchange in the atomic dynamics between 960 and 1200 K. Above this range,normal liquid-like behavior is found; at lower temperatures, we find aresidual diffusivity and cooperative atomic Motion. Atomic jumps areprocesses smeared out in time and space over continuous rather than discretescales.
