Using density functional theory, we have studied the electronic and magnetic properties of zinc blende (MnN)(1)/(AlN)(1), (MnN)(1)/ (GaN)(1), and (MnN)(1)/(InN)(1) superlattice in the (001) direction. We demonstrate the possibility to obtain half-metallic ferromagnets in (MnN)(1)/(GaN)(1), and (MnN)(1)/(InN)(1) and (MnN)(1)/(AlN)(1) with a total magnetic moment close to 8 mu(B). The analysis of the partial density of states reveals that ferromagnetism can be explained by the strong p-d hybridization of N and Mn atoms. The magnetism comes essentially from the d orbitals of Mn atoms, and to less extent from the interstitial region.
