The effect of magnetism on the ground state structures has been investigated by means of first-principles, density-functional calculations. In addition to the experimentally observed CsCl-type ground-state structure for FeCo stoichiometric alloys, our spin-polarized calculations predict several new ordered structures for iron-rich alloys. In particular, our results show that Fe3Co alloys are energetically stable for a number of ordered structures. (C) 2004 Elsevier B.V. All rights reserved.
