Abstract
The evolution of Ll(1) 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 me asurements of residual resistivity. An excellent agreement between both exp erimental methods results, using the well-known Rossiter formalism for eval uation of LRO-parameter from resistivity measurement. Results of X-ray diff raction were used to study the changes of the lattice parameter and the lat tice distortion by the rhombohedral superstructure as a function of the deg ree of LRO.
