Magnetic Moment of Mn Atoms in fcc Co–Mn Alloys

The properties of the magnetic moments of Mn atoms in ferromagnetic fcc Co–Mn alloys were investigated by means of neutron magnetic diffuse scattering and by the measurement of the anisotropy of the electrical resistivity under the magnetic field. By comparing the cross-sections between polarized and unpolarized neutrons, it has been suggested that there are two kinds of Mn atoms; the one with parallel and the other with antiparallel moment to the bulk magnetization. The concentration dependence of the number of Mn atoms with parallel moment has been estimated by the resistance experiment, based on the two current model. These facts can be explained by a spin reversal model with some improvements.
