An X-ray Scattering and Simulation Study of the Ordering Kinetics in CuAu
arXiv:cond-mat/9806141 · doi:10.1209/epl/i1998-00409-9
Abstract
A detailed numerical and experimental study of the ordering of the low temperature tetragonal phase of CuAu is presented. The numerical simulations are based on a coarse-grained free energy derived from electronic structure calculations of CuAu, while the experimental results are obtained from in situ x-ray scattering. Both theoretical and experimental work indicate a subtle kinetic competition between the ordered tetragonal phase and the metastable modulated phase.
