抄録

The magnetic moment of atoms is calculated as a function of the atomic composition on the nearest-neighbor shell, of the alloy concentration, and of a short-range-order parameter for Fe–Ni alloys in bcc and fcc phase and Fe–Co alloy in bcc phase, by use of an effective medium theory developed by Miwa and the author. The intra-atomic electron-electron interactions are assumed to be treated within the Hartree-Fock approximation, and the effective medium is determined self-consistently. The behavior of the moment caused by the change of local environment is explained in terms of the total and local density of states on the basis of numerical calculation. In a saturated ferromagnet the width of the distribution of the moment must be small for each constituent. In an unsaturated ferromagnet this width is allowed to become large.
