The crystal structure and magnetic properties of Fe2MAl compounds for M = V, Cr, Fe, Co and
Ni were investigated by X-ray, magnetostatic and Mössbauer effect methods. It was found that the
investigated compounds possess not perfectly ordered fcc structure of the L21-type.
With increasing number of 3d electrons of M component the transition from the paramagnetic to
ferromagnetic behaviour follows. Mössbauer spectra were analysed by a hyperfine field distribution
method. They are characterictic of the ferromagnetic phase for M = Fe, Co and Ni and indicated the
early observed preference of these atoms for the Fe sites.
