Mössbauer study of some intermetallic compounds Fe80-xNixB20 (x = 8, 16, 24, 28)

Abstract

Fe-based nanocrystalline alloys were prepared by the melt-spinning technique and characterized by X-ray diffraction, magnetostatic and Mössbauer effect methods. The Mössbauer spectroscopy allows to study the local environment of the Fe atoms in the investigated Fe80 xNixB20 (x 8, 16, 24, 28) compounds and showing the changes in the structure due to the changing of Ni addition. Combination of X-ray diffraction and Mössbauer spectroscopy results confirm formation of different number of phase complex, including the -FeNi, -FeNi, FeB, Fe2B, Fe3B in the investigated materials together with increase of Ni content.
