Abstract

We reviewed the present situation of the α″-Fe16N2 problem for α″-Fe16N2 films with and without a giant magnetic moment in connection with structure and magnetic moment. The results of X-ray diffraction and transmission electron microscopy analysis did not show any difference between α″-Fe16N2 films with and without a giant magnetic moment. However, the Mössbauer spectra were quite different from each other. The hyperfine field of Fe16N2 film synthesized by the present authors splits into three hyperfine field interactions. However, for the Fe16N2 with a giant magnetic moment, the hyperfine field interaction did not split and is almost the same as that of pure α-Fe. Therefore, the interpretation of Mössbauer spectra is the key item to solving the α″-Fe16N2 problem.
