在295 °K下测量了h. c. p.氮化铁-Fe3.2N粉末样品的穆斯堡尔效应。测量表明，在这种材料中存在两种不同环境的Fe原子。这与先前的X射线研究一致，通过X射线研究发现，在α-铁氮化物中，N原子以这样的方式高度有序，例如在α-Fe 3.2N中，Fe原子在其最近的邻域内具有一个或两个N原子。此外，已测得α-Fe 3.2N中Fe原子的平均磁矩为1.97 μB。利用这个值和穆斯堡尔数据，可以估算出Fe原子的磁矩。得到的矩分别为2.4 μ B和1.9 μ B。这些值被解释为类似的考虑，通过该f.c.c.γ′-氮化铁Fe 4 N先前已在文献中解释。
The Mössbauer effect has been measured on powder samples of the h.c.p. iron nitride ϵ‐Fe3.2N at 295 °K. The measurements indicate, that there are two kinds of Fe‐atoms with different environments in this material. This is in accordance with previous X‐ray investigations by which it was found that in ϵ‐iron nitrides the N‐atoms are highly ordered in such a way that e.g. in ϵ‐Fe3.2N the Fe‐atoms have either one or two N‐atoms within their nearest neighbourhood. Furthermore the average magnetic moment of the Fe‐atoms in ϵ‐Fe3.2N has been measured to be 1.97 μB. Using this value together with the Mössbauer data the magnetic moments of the Fe‐atoms are estimated. The moments obtained are 2.4 μBand 1.9 μBrespectively. These values are interpreted by similar considerations by which the magnetic structure of the f.c.c. γ′‐iron nitride Fe4N has been explained previously in the literature.
