Tight-binding LMTO calculations on the stability of a new multiple spin-density-wave state in γ-Fe

The electronic structure calculations of the triple-Q spin-density-wave (3-Q) state in gamma -Fe, which has recently been found in the molecular-dynamics calculations, have been performed on the basis of the tight-binding LMTO Hamiltonian and the recursion method. It is demonstrated that the 3-Q state is more stable than the single Q (Q = 0.6) helical state which was found in the past calculations. (C) 2001 Elsevier Science B.V. All rights reserved.
