The spectra of liquid 85%Fe5%Ni10%S (Tm = 1650 K) and liquid 85%Fe15%Ni have been studied by means of inelastic neutron scattering. Our aim was to explore at high frequencies some observed anomalies as reported from ultrasound studies. Contrary to the behavior of the pure liquid-metals, the phase velocity of the observed excitation for the sulfur-containing sample increases with temperature while their damping decreases. On the other hand, data of the binary Fe/Ni alloy do not show such an anomalous behavior.
