Abstract:	We have calculated spin-polarized electronic band structures of cubic antiperovskite metal nitrides (Fe₄N, Fe₃CoN, FeCo₃N and Co₄N) by the full-potential method with mixed basis augmented plane wave plus local orbitals. It was shown that FeCo₃N has an energy gap of 0.2 eV at the Fermi level in the up-spin band and hence its half-metallic behavior is expected.

Keywords:	Energy band calculation Half metal Metal nitride
