a A region containing a crystal-like supercluster in the Zr50Cu45Al5 bulk metallic glass, which was analyzed by hybrid reverse Monte Carlo simulations of the structure by incorporating medium-range structure information from fluctuation electron microscopy data and short-range structure preference from an embedded atom potential.38 The atoms are colored by the fraction of pentagons in their Voronoi polyhedron. b Probability distribution of bond orientational order (w6) in a 12,000-atom MD model, together with the characteristic w6 for ideal fcc and icosahedron cluster;39 Structural connection between the ideal icosahedron, distorted icosahedron, and fcc cluster are schematically shown on the top of b. a is adapted from ref. 38 and b from ref. 39
