The Oxygen Vacancies Correlated Ferromagnetism in Transition Metal-Doped ZnO Nanowires

摘要

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