Rjd. Tilley et Rp. Williams, A SHIFT-LATTICE DESCRIPTION OF SOME FACE-CENTERED-CUBIC ALLOY SUPERSTRUCTURES - PART 2 - 2-DIMENSIONAL STRUCTURES, Journal of materials chemistry (Print), 8(7), 1998, pp. 1613-1618
The structures of the experimentally prepared binary alloys Au31Mn9 (t
wo forms), Au72Mn21, Au95Mn28, Au27Mn8, Au167Mn49 and Au3Mn tone form)
, have been analysed and found to be two-dimensional shift-lattices. I
t is shown that both the Au and Mn atom arrays lie upon separate but c
omplementary shift-lattices. The known structures form only a small pa
rt of an infinite family of commensurate and incommensurate structures
which can be constructed by smoothly varying the shift-lattice parame
ters applicable to the known phases. The two-dimensional shift-lattice
structures described here are shown to be constructed from fragments
of simpler one-dimensional shift-lattices analysed previously.
