Description
The fine structure of the equilibrium diffuse x-ray scattering of a Cu3Au(110) crystal reveals an unexpected temperature dependence of the fourfold peak splitting associated with Fermi surface imaging. The separation of the split diffuse maxima increases with temperature corresponding to a proliferation of correlated microdomains in a real space picture. As current alloy theories based on the calculation of the configurational energy do not cover such a temperature dependent microstructure, the results of this study outline the importance of the entropy contribution to the alloy free energy. copyright 1996 The American Physical Society
