1926 Jrnl. Inst. Metals 36 495 The metals of Groups I. and III. should utilize a complete lattice of the rock-salt type, the sub-lattice of the positive ions being face-centred cubic. In exception to this, the sub-lattice of the alkalis must be considered as face-centred tetragonal.
1959 J. Pouwelsen et al. tr. W. F. de Jong Gen. Crystallogr. ii. 101 Either the direct lattice..is congruent (similar) with the elementary Bravais lattice, or one is a sub-lattice of the other.
1976 Physics Bull. July 294/2 In a crystal the atomic lattice can divide into two interpenetrating sublattices so that most, if not all, of the neighbours of an atom on one sublattice belong to the other.
2010 N. A. Spaldin Magn. Materials (ed. 2) viii. 96 We can think of antiferromagnets as containing two interpenetrating and identical sublattices of magnetic ions.
