Molecular dynamics simulation of Al₉₈Sm₂ MG. (A) Potential energy versus temperature or time. (B) Three-dimensional (3D) view of atomic configurations, T = 600 K. (C) Dynamic evolution of string-like motions. The plot shows the fraction of atoms in string-like configurations to the total number of atoms as a function of temperature for quenched and annealed MG as indicated. (D) 3D view of the string-like configurations, T = 380 K and δt = 100 ps.
