Abstract
The authors present a Monte Carlo study of a dilute system of interacting classical quadrupoles on an HCP lattice for quadrupole concentrations X=0.68 and X=0.53. Within their computation time limits which were 4*105 MCS per quadrupole for a sample of 96 sites and 105 MCS per quadrupole for a sample of 216 sites, they find a progressive growth of the local quadrupolarisations. However, an analysis of the orientational fluctuations sets a lower bound of the order of 100 on the number of correlated quadrupoles responsible for this growth.Keywords
