Abstract
A time-of-flight linac neutron diffraction study was performed on splat cooled Ni 60Nb 40 and Fe 81B 19 metallic glass samples. The structure factor was measured up to high momentum transfers, Q max = 26 A ̊ −1 with resulting high resolution (Δr ∼ 0.24 A ̊ ) for the distribution function obtained by Fourier transformation. For Fe 81B 19, partial coordinations could be resolved resulting in r FeFe = 2.55 A ̊ , r FeB = 2.18 A ̊ first neighbour atomic distances and n FeFe = 10.6, n FeB = 1.95, n BFe = 8.3 partial coordination numbers. For Ni 60Nb 40, no splitting of the first peak of the distribution function was observable.
