Absence of spin glass order in the 2D site-diluted triangular antiferromagnet

The authors have studied the site diluted triangular antiferromagnet by constructing ground state spin configurations for a variety of defect concentrations. They find there is no spin glass ordering at any temperature in the dilute limit or near the percolation threshold and argue that there is none at intermediate concentrations. This conclusion is also supported by a real-space renormalisation treatment.
