Theoretical predictions and later experimental findings of room-temperature ferromagnetism in Mn doped GaN have awoke considerable interest in nitrides as promising materials for spintronics. The ferromagnetic GaN:Mn could be a potential candidate for spin-polarization field emitter and might be useful in the development of all semiconductor spintronic devices. However, the physical mechanisms of possible room-temparature ferromagnetism in GaN:Mn are not well understood yet. Here, we provide critical review of existing theories and experimental data for GaN:Mn and discuss prospects of ferromagnetism in GaN doped with other transition metals.
