While Mg has been found previously to prefer the octahedral site, we find here that Zn prefers the tetrahedral substitutional site. The EPR signatures are found to be distinct for the two sites. Good agreement with experiment is found for the $g$-tensor and hyperfine interaction for Mg$_\\mathrm{Ga2}$ and predictions are made for the Zn case.","authors_text":"Dmitry Skachkov, Walter R. L.
