抄録

Using the pulsed-neutron diffraction technique, we performed in situ measurements of structural ordering in the ternary alloy CuMnPt₆. The diffraction patterns at various temperatures give a direct observation of a double-step ordering: disorder to Cu₃Au type order as an ordering within the fundamental face-centered cubic lattice to subdivide the lattice into two sublattices formed by face-centered sites (first sublattice) and corner sites (second sublattice) at 968°C; and Cu₃Au type order to ABC₆ type order as an ordering within the second sublattice to subdivide the lattice further into two sublattices formed by alternating (111) planes at 746°C. The order parameters for the ABC₆ type structure experimentally estimated by the method of static concentration waves indicate that the primary ordering developed almost completely, but the secondary ordering remained incomplete.
