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

Abstract The electronic structure calculations of the triple- Q spin-density-wave (3- Q ) state in γ-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.
