| Abstract: | X-ray diffraction was used to determine temperature ranges of annealings that allow the stabilization of the D03 and B2 superstructures in Fe-Al alloys at room temperature upon cooling them at a given rate. A substantial effect of the long-range-order type on the magnetic properties, such as the magnetic-ordering temperature, average magnetic moment per Fe atom, average hyperfine magnetic field at 57Fe nucleus, and coercive force, is demonstrated using the Fe70Al30 alloy as an example. |
