摘要：

A quenched equilibrium state of a 3165.1 at. % Zn single crystal was investigated by elastic diffuse neutron scattering. The short-range order intensity showed maxima that could be related to the flat portions of the Fermi surface perpendicular to the 110 directions. Effective pair potentials Vlmn were determined from 71 short-range order parameters lmn obtained from a fit to the diffuse intensity. Furthermore, 40 linear displacement parameters were also extracted. A dominant V110 of 18 meV was obtained. Based on a Monte Carlo simulation, an ordered low-temperature phase Cu3Zn with the DO23 structure and a critical temperature of 330 K is suggested. © 1990 The American Physical Society.
