Abstract
We report the use of targeted - and -type chemical perturbations to manipulate high- ferromagnetism in and in predictable and reproducible ways. We demonstrate a clear correlation between nitrogen and high- ferromagnetism for and an inverse correlation for , both as predicted by recent theoretical models. These chemical perturbations reveal rich possibilities for exerting external control over high- spin ordering in diluted magnetic semiconductors.
