摘要：
The Fourier-transformed exchange matrix for the crystalline structure of Mn3Sn and Mn3Ge is analyzed in the case of a propagation vector parallel to the hexagonal principal axis and two modes of spin ordering are predicted, a helix of ferromagnetic basal net planes and a helix of triangular basal net planes. The effect of anisotropy energies is studied for the triangular spin ordering with zero propagation vector to uniquely determine the spin configuration and to account for the observation. Triangular helix, observed in Mn3Sn at low temperatures, is also discussed. © 1979, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
