Abstract The band structure of Fe-N film is studied by angle resolved photoemission spectroscopy. It is found that the 3d band of Fe-N film disappears due to the hybridization of Fe 3d states and N 2p states. The result can account for the less ferromagnetism and conductivity of Fe-N film when compared with those of Fe film. This finding indicates that the high content of nitrogen can significantly change the band structure of iron nitrides, which exceeds the conventional theoretical prediction. The present work may evoke the re-recognization to the effect of coupling of Fe and N, and promote the further research of band structure of iron nitrides.

角分辨光电子能谱研究氮化铁的能带结构

摘要 利用角分辨光电子能谱研究了Fe-N薄膜的能带结构。发现Fe-N薄膜的3d带由于Fe 3d态和N 2p态的杂化而消失。结果可以解释与 Fe 膜相比，Fe-N 膜的铁磁性和导电性较低。这一发现表明，高含量的氮可以显着改变氮化铁的能带结构，这超出了常规的理论预测。目前的工作可能会引起人们对Fe和N耦合效应的重新认识，促进氮化铁能带结构的进一步研究。
