Abstract

The magnetic properties of 3d transition metal (TM = V, Cr, and Mn)-doped ZnO nanowires (NWs) with and without oxygen vacancy are investigated by ab initio calculations. The magnetic moments can be induced by TM impurities in ZnO NWs, localized on the 3d TM atoms and their neighboring O atoms. Furthermore, the ferromagnetism in V-, Cr-, and Mn-doped ZnO NWs is strongly correlated with oxygen vacancies.
