The ordered Au 4 Mn alloy has been investigated by electron diffraction, using oriented, evaporated films. This ordered alloy has been found below about 400°C to have the body-centred tetragonal unit cell which is 2.5 times as large as the fundamental cell in volume. The structure is isomorphous to that of Ni 4 Mo and belongs to the space group I 4/ m – C 4 h 5 . This structure is not the so-called anti-phase domain structure. Some qualitative discussions have been given of the structural transition between the ordered Au 4 Mn and Au 3 Mn and of the origin of ferromagnetism in Au 4 Mn, on the basis of the proposed structure model.
