(b1) The longitudinal structure factor S(q) under a compressive stress of 10, 500, 1000, and 1500 MPa, respectively. (b2) Difference plot of S(q), between 10 MPa and higher stress levels. (c) Schematic illustration of a hypothetical amorphous structure showing local packing of solvent atoms (A), solute-centered clusters (B), and super-clusters (C) in a metallic glass. The gray color in B and C denotes the outmost atomic shell filled with a majority of solvent atoms. The dark spot in B represents the solute atom of a solute-centered cluster, while the dark area in C represents the inner solute-enriched region within a super-cluster.^[146] With permission from Physical Review Letters.
