Abstract

Antiferromagnetically coupled Ising s =3 spins on a triangular lattice are\nvery close to ordering at zero temperature. The low temperature behaviour of a\ntriangular lattice with Ising spins s =3 has been simulated by using both\nGlauber and Kawasaki dynamics. The formation of misfit clusters, which are\nessential for destabilizing the ordered state, are inhibited by the use of\nKawasaki dynamics. The sublattice susceptibilities and the sublattice order\nparameter are found to depend qualitatively on the dynamics used so that robust\nordering occurs when Kawasaki dynamics are employed. The thermal behaviour that\nis found for the spin model with Kawasaki dynamics gives insight into the\nobserved ordering of side chains seen in a tetraphilic liquid crystal.\n
