The stability of the ferromagnetic state in ZnO-, ZnS-, ZnSe- and ZnTe-based DMSs is investigated systematically and materials design for ferromagnetic DMSs is given. In all host materials, it is found that V- and Cr-doped systems are ferromagnetic and Mn-doped systems are spin-glass state. On the other hand, for Fe-, Co- and Ni-doped systems, the ferromagnetic state is stable in ZnO-based DMS, however, the spin-glasss state is stable in ZnS-, ZnSe- and ZnTe-based DMSs. The carrier-induced ferromagnetism in ZnO-based DMSs is also investigated and it is found that their magnetic states are controllable by changing the carrier density. Analysing the calculated density of states, the mechanism to stabilize the ferromagnetic state in the DMSs is discussed. Citing Literature Volume229, Issue2January 2002Pages 673-680 RelatedInformation
