DYNAMIC STRUCTURE FACTOR OF THE METALLIC GLASS Ni 24 Zr 76

The dynamic structure factor S(Q, ω) of the metallic glass Ni 24 Zr 76 was investigated for momentum transfers Q between 0.8 ≤ Q ≤ 2.5 A −1 and energy transfers hM below 20 meV using neutron inelastic scattering techniques. The experiments were done at the time focussing time-of-flight (t-o-f) spectrometer IN6 at the HFR of the Institut Laue-Langevin in Grenoble. The metallic glass and the same glass after crystallization were measured at 380K.
