The structural anisotropy of a metallic glass, Fe81B13Si4C2, deformed
under stress to induce anelastic deformation, was studied by synchrotr
on X-ray diffraction. In addition to the l = 2 bond orientational orde
r reported earlier, the l = 6 orientational order predicted by compute
r simulation was observed. Even though the magnitude of the l = 6 term
was smaller than predicted, the result demonstrates the utility of th
e network concept in describing the structure of metallic glasses.
