Abstract
Both metal atom components of a number of binary alloy structures, mai nly occurring in the Au-rich region of the Au-Mn system, have been ana lysed as shift-lattices. It is shown that both atom types lie upon sep arate complementary shift-lattices. All the structures can be reproduc ed by a smooth variation of the shift-lattice parameters. Those found experimentally form only a small set of the infinite family of commens urate and incommensurate structures which can be constructed via the s hift-lattice method. The diffraction patterns of these phases can read ily be derived and the relationship of the diffraction patterns observ ed to the separate components from each of the contributing shift-latt ices is described.
