Short-Range Quadrupolar Order on a Dilute Simple-Cubic Lattice

Abstract

Computer experiments provide evidence that an intermolecular quadrupolar interaction on some crystal lattices can lead to short-range rotational "freezing" whose characteristics are similar to those of spin-glass ordering. Local order parameter and susceptibility are calculated as a function of temperature for a simple-cubic lattice, and the effects of dilution on the low-temperature limit of the order parameter are also discussed.
