Les propriétés électroniques de (Ga,Mn)N ont été étudiées par spectroscopie d'absorption des rayons X au seuil K du Mn. Des calculs ab-initio ont été utilisés pour interpréter les spectres d'absorption de (Ga,Mn)N. Deux pré-pics sont présents dans le seuil du Mn: le premier pré-pic est attribué aux transitions électronique vers les états 3d du Mn de spin up, tandis que le second pré-pic correspond aux transitions vers les états 3d du Mn de spin down. Cette interprétation nous permet de déterminer que l'état électronique du Mn dans (Ga,Mn)N est Mn3+: deux pré-pics sont présents dans les spectres d'absorption du Mn3+ et un seul pré-pic reste dans les spectres du Mn2+. Ce changement des spectres a été vérifié expérimentalement sur des échantil...
