| 中文摘要 | The electronic structure and magnetic properties of Fe-based binary half-Heusler alloys Fe(2)Z (Z=In, Sn, Sb and As) have been studied. It is found that binary Fe(2)Z has a site preference similar to normal ternary ones. Hybridization between the d states of Fe (A) and Fe (B) leads to the formation of a d-d band gap near E-F. This gap is broadened and shifted to low energy as Z varies from In to Sb, which makes Fe2Sb a half-metal. The half-metallicity of Fe2Sb is insensitive to the lattice distortion. The spin polarization ratio is always 100% from 5.6 angstrom to 6.2 angstrom. The spin polarization of Fe2As is also high at equilibrium lattice constant. With a small expansion of the lattice, it becomes an ideal half-metal. Fe(2)Z alloys are all ferromagnets with parallel aligned Fe spin moments. (C) 2012 Elsevier B.V. All rights reserved. |
