Abstract
⺠The Mn doped Ge3N4 switch from semiconductor to half-metal as the Mn concentration increases. ⺠The magnetic moment of Mn ion increases from 0.82μB to 2.50μB as the Mn concentration increases. ⺠The ferromagnetic coupling between Mn atoms induces the high spin-states of Mn 3d electrons. ⺠The ferromagnetic coupling between Mn atoms also results inthe half-metallicity of the system.
