| 中文摘要 | The electronic structure and magnetic properties of new Fe-based Heusler alloys Fe(2)TiZ (Z = Ga, Ge, As, In, Sn and Sb) have been studied by first-principles calculations. In these alloys, the 24-electron Fe2TiGe, Fe2TiSn are nonmagnetic semiconductors and other compounds are all ferrimagnetic metals. Fe2TiAs and Fe2TiSb are predicted to be half-metals with 100% spin polarization. The spin polarization ratio in Fe2TiGa and Fe(2)Tiln is also quite high. The calculated total moment for Fe2TiAs and Fe2TiSb is 1 mu(B), which is mainly determined by the Fe partial moment. The half-metallicity of Fe2TiSb is stable under lattice distortion. The spin polarization of Fe2TiSb is found to be 100% for the lattice variation in a range of 5.6-6.1 angstrom, which is attractive in practical applications. (C) 2012 Elsevier B.V.
