鐵氧化物和鐵氮化物混合系統是藉由合成氮化鐵(FN)的退火所研究出來的。系統的研究了樣品的物理及化學特性。根據觀察，FN在氧化時的多相變，是因為氧化溫度所造成的。ε-Fe3N 和 α-Fe2O3 奈米顆粒的形成可以藉由XRD研究得到證明。利用超導量子干涉儀的磁力計可以發現，磁滯曲線可以得知樣品隨著氮原子的減少而減少超順磁特性。對於溫度的磁化分佈表示觀察到的氮化鐵相的鐵磁特性可歸因於由氮數量和晶格中的限制引起電子自旋態的重新分佈。

Mixed iron oxide and iron nitride systems were investigated by annealing synthetic iron nitride (FN). The physical and chemical properties of the samples were studied systematically. According to the observation, the multiphase transformation of FN during oxidation is caused by the oxidation temperature. The formation of ε-Fe3N and α-Fe2O3 nanoparticles can be confirmed by XRD studies. Using the magnetometer of the superconducting quantum interferometer, it can be found that the hysteresis curve can tell that the superparamagnetic properties of the sample decrease with the reduction of nitrogen atoms. The magnetization distribution versus temperature indicates that the observed ferromagnetic properties of the iron nitride phase are attributable to the redistribution of electron spin states caused by the nitrogen amount and confinement in the lattice.
