英文摘要 | Based on the density functional theory, we study the magnetic coupling properties of mn-doped zno nanowires. for the nanowires with passivated surfaces, the antiferromagnetic state is found and the mn atoms have a clustering tendency. when the distance between two mn atoms is large, the system energetically favors the paramagnetic or spin-glass state. for the nanowires with unpassivated surfaces, the ferromagnetic (fm) coupling states appear between the two nearest mn atoms, and the zinc vacancies can further stabilize the fm states between them. the electrons with enough concentration possibly mediate the fm coupling due to the negative exchange splitting of conduction band minimum induced by the s-d coupling, which could be useful in nanomaterial design for spintronics.
