Electronic and magnetic properties of several IIA-V compounds have been analyzed using ab initio calculations. Two crystal structures have been considered, zinc blende (zb) and rock salt (rs), as well as the observed monoclinic phase for SrN. The results indicate that IIA-V nitrides in the rs phase are ferromagnetic half-metals. Ferromagnetism of cubic IIA-V compounds originates in the spin polarization of the p-shell of anions, as given by Hund's rule, which persists in solids after formation of bonds. Magnetism of the monoclinic SrN is due to its mixed valence character.
