Magnetic Phase Separation and Magnetic Moment Alignment in Ordered Alloys FE₆₅Al_35−xM_x (M_x = Ga, B; x = 0; 5 at.%)

(a) Mössbauer spectra measured without external field and in an applied external magnetic field = 5 T for the alloys Fe₆₅Al₃₅ and Fe₆₅Al₃₀Ga₅. The spectrum components corresponding to the subsystems of the ferromagnetic type (black colour, shown by the arrow) and of the SDW (blue color) are presented, as well as the resulting spectrum envelope; (b) the HFF distributions of the ferromagnetic-type component; (c) the shape of the spin density wave; (d) the HFF distribution resulting from the SDW shape.
