| Abstract: | The S(Q) structure factor of (Ni65Fe35)77B23 metallic glass was measured by time-of-flight neutron diffraction up to 24 Å?1 momentum transfer. The distribution of transition metal-boron and transition metal-transition metal first neighbour atom pairs is resolved in the distribution function obtained from S(Q) by Fourier transformation. The distances of these first neighbours pairs, the width of their distribution, the partial coordination numbers and the short range order parameter are given. The results on (Ni65Fe35)77B23 and on the previously studies Fe81B19 amorphous alloys are compared. |
