Summary Magnetic properties of Fe nitrides have been re-examined by57Fe Mössbauer spectroscopy. Hyperfine magnetic fields for α″-Fe16N2 are 30, 31 and 39T at 298K, but the averaged hyperfine field is 33T and nearly equal to the value of pure α-Fe. σ-Fe2 N is an antiferromagnet below 9K having a small magnetic moment less than 0.1 μB, although γ′-Fe4N and ε-Fe3–2N are ferromagnets. ZnS-type FeN is non-magnetic at 4.2K. Mössbauer spectra obtained from NaCl-type FeN are complex and some Fe atoms in this nitride show a surprisingly large hyperfine magnetic field of 49T.
