The evolution of L11 long-range order (LRO) in Cu-50 at%Pt was studied as a function of temperature in parallel by means of X-ray diffraction and measurements of residual resistivity. An excellent agreement between both experimental methods results, using the well-known Rossiter formalism for evaluation of LRO-parameter from resistivity measurement. Results of X-ray diffraction were used to study the changes of the lattice parameter and the lattice distortion by the rhombohedral superstructure as a function of the degree of LRO.
