| Abstract: | Inelastic neutron scattering experiments performed on carefully prepared single crystals of NiₓAl₁minus/x/ (x = 50, 58, 62.5 at. percent) reveal an anomaly in the /ζ/zeta/0)-TA mode whose position in /zeta/ depends linearly on x. The temperature dependent studies of the 62.5/percent/ alloy show marked softening of the phonon energy at /zeta/ = 1/6. At the same temperatures, an elastic central peak develops. At T/sub M/ = 80K a new structure develops which exhibits a modulation at nearly, but not exactly, /zeta/ /equals/ 1/7. 11 refs., 2 figs. |
