The magnetic properties, crystal and electronic structure for Fe1-xNix (x=0.30, 0.325, 0.375) alloys and austenitic steel were studied using magnetostatic, Mössbauer effect methods, X-ray diffraction and X-ray photoelectron spectroscopy. The compositions of the investigated Fe-Ni alloys were chosen like that to exist on left, right and in inside of invar range. Two different magnetic moments (low and high) of Fe atom were observed. Measurement results do not show antiferromagnetic order in Fe-Ni alloys.
