摘要
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.
