a b s t r a c tSpin-polarized first-principles total energy calculations have been performed to study the structural, electronic and magnetic properties of Mn 3 N 2 (0 0 1) surfaces. It is found that three surface terminations are energetically stable, in agreement with previous scanning tunneling microscopy experiments that have found three different electronic contrasts in their images. It is also found that in all three cases, the topmost layer has a MnN stoichiometry. Density of states calculations show a metallic behavior for all the stable structures with the most important contribution close to the Fermi level coming from the Mn-d orbitals. Our Tersoff-Hamann scanning tunneling microscopy simulations are in good agreement with previous experimental results.

Interfacial magnetic coupling interactions between D022-Mn3Ga and ultrathin Fe films were studied using first principles calculations. Based on the calculations of surface energy and interface energy, it is demonstrated that Mn-Ga/Fe is the most stable interfacial structure. As a result, four possible coupling states between D022-Mn3Ga and Fe films may be present by considering the relative direction of magnetic moment for the interfacial and inner-layer Mn atoms. Their corresponding energies were calculated by varying the Fe atomic layer thicknesses from 1 to 6 monolayers. It is found that the antiferromagnetic coupling energy in D022-Mn3Ga/Fe films with an anti-parallel magnetic moment of the interfacial and inner-layer Mn atoms is the smallest one, regardless of the Fe layer numbers. The possible mechanism about the antiferromagnetic interactions between D022-Mn3Ga and ultrathin Fe films was analyzed by the orbital-resolved electronic density of states.
