A poor reproducibility with respect to the magnetic properties is found in these samples. Our results show strong indications that defects with a concentration of the order of 10(19) cm(-3) might play an important role for the magnetic properties. Positron annihilation spectroscopy does not support a direct connection between the ferromagnetism and the Ga vacancy in GaN: Gd. Oxygen codoping of GaN: Gd promotes ferromagnetism at room temperature and points to a role of oxygen for mediating ferromagnetic interactions in Gd-doped GaN."],["dc.description.sponsorship","Deutsche Forschungs Gesellschaft [SFB 602]"],["dc.identifier.doi","10.1103/PhysRevB.84.081201"],["dc.identifier.isi","000293774600001"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/7962"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/22370"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","1098-0121"],["dc.relation.orgunit","Fakultät für Physik"],["dc.rights","CC BY 3.0"],["dc.title","Tracking defect-induced ferromagnetism in GaN:Gd"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
