采用脉冲激光沉积法在Al基体上制备了具有岩盐结构的单相γ-FeN薄膜。测量了它的穆斯堡尔谱和粉末X射线衍射图，发现γ-FeN是反铁磁的，在5 K温度下具有30 T的超精细磁场。发现它的Néel温度为220 K。还观察到一个较小的组件，具有较高的超精细磁场的49 T在5 K。它被认为是源于γ-FeN中的缺陷。
A single-phaseγ‴-FeN film with the rock-salt structure was produced by pulsed laser deposition of Fe onto an Al substrate in a N2atmosphere. Its Mössbauer spectra and powder X-ray diffraction patterns were measured.γ‴-FeN was found to be antiferromagnetic exhibiting a hyperfine magnetic field of 30 T at a temperature of 5 K. It was found to have a Néel temperature of 220 K. A minor component with a higher hyperfine magnetic field of 49 T at 5 K was also observed. It is thought to originate from defects inγ‴-FeN.
