Atomic Motion in Amorphous Ni81B19 Studied by Reverse Monte Carlo and Molecular Dynamics Simulation
Published online by Cambridge University Press: 15 February 2011
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 significant change in the atomic dynamics between 960 and 1200 K. Above this range, normal liquid-like behavior is found; at lower temperatures, we find a residual diffusivity and cooperative atomic Motion. Atomic jumps are processes smeared out in time and space over continuous rather than discrete scales.
