Abstract
By using first-principles calculations, the magnetic properties of a SnO2 quantum dot (QD) are investigated. It is found that dangling bonds (DBs) are equated with Co (Ni) dopants, which can induce magnetic moments in SnO2 QDs. Thus, the QD shows very abundant variation of the magnetic properties by combining dopants with DBs. The changes of magnetic moments can be explained well by a carrier modulation model.
