A time-of-flight linac neutron diffraction study was performed on splat cooled Ni60Nb40 and Fe81B19 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 Fe81B19, partial coordinations could be resolved resulting in r FeFe = 2.55 A , r FeB = 2.18 A first neighbour atomic distances and nFeFe = 10.6, nFeB = 1.95, nBFe = 8.3 partial coordination numbers. For Ni60Nb40, no splitting of the first peak of the distribution function was observable. |
