X-ray and ND. (A) Structure determination for Ni₈₀P₂₀ MG by XRD (top) analysis, the insets show the EXAFS spectra. Bottom left is the atom packing model reconstructed by RMC method. Bottom right shows the local cluster and the packing of a variety of clusters (Adapted from ref. [78]. Copyright©2006, Springer Nature). (B) (left) The structure factors of the Al₈₉La₆Ni₅ MG from XRD experiment and the inverse Monte Carlo (IMC) simulation, showing a satisfactory match between simulation and experiments. (right) An atomic slab of Al₈₉La₆Ni₅ MG obtained from IMC modeling with thickness of 3.5 Å, showing the random distribution of La and Ni atoms mostly surrounded by Al atoms (Adapted from ref. [79]. Copyright©2008, Elsevier). (C) (top) XRD pattern of Ce₅₅Al₄₅ MG obtained in situ during the compression and decompression experiments. (bottom) The two-dimensional (2D) projections of the 3D isosurfaces of the electron charge density from ab initio calculations for the two amorphous states (Adapted from ref. [80]. Copyright©2007, Springer Nature). (D) Two reduced PDF G(r) of glassy Cu_64.5Zr_35.5 obtained by Fourier transforming the experimental structure factor S(q) (the inset) with two termination values (q_max) (Adapted from ref. [87]. Copyright©2009, Springer Nature). (E) (top) PDFs of Cu-Zr-Al BMGs with different compositions. (bottom) Reduced PDFs for the crystalline products and the as-cast amorphous state of studied Zr-Cu-Al alloys using the exponential function fitting (the dotted lines) (Adapted from ref. [88].
