It has been obtained by the experiments of diffuse scattering of neutrons that the magnetic moments of Fe and Mn atoms in α-FeMn alloys are 2.23±0.01 and 0.7±0.25μ_B at 0 K, respectively. the magnetic moment of Fe agrees with the theoretical value obtained by CPa calculation, while that of Mn is smaller than the theoretical one. The spatial fluctuation of the magnetic moment of Fe and Mn atoms cannot be observed within the experimental accuracy. The temperature dependence of the magnetic moments of Fe and Mn has been studied, and we have found an anomalous behavior in <μ_<Mn>>. This behavior cannot be explained by the molecular field theory proposed by Jaccarino et al.
