One-dimensional antiphase structure of Au22Mn6 studied by high-voltage, high-resolution electron microscopy

One-dimensional antiphase structure of Au22Mn6 studied by high-voltage, high-resolution electron... Au-Mn alloys near the composition of 20% Mn have been investigated by the superstructure imaging technique using a 1 MV electron microscope. A new superstructure, Au22Mn6, was proposed directly from the high-resolution images. The structure is based on the Au4Mn structure of Ni4Mo (D1a) type and consists of parallel columns with a width of three Mn-atom rows, and the columns are separated by one-dimensional antiphase boundaries parallel to the (210) plane of the fundamental f.c.c. structure. Structural modulation and local disorder were also revealed at the atomic scale. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Crystallographica Section A: Crystal Physics, Diffraction, Theoretical and General Crystallography International Union of Crystallography
