Fe 2p3/2 and 2p1/2 X-ray photoelectron spectroscopies (XPS) reveal the electronic hybridization between the Fe atoms and the adjacent N atoms, whereas a multipeak analysis suggests the charge-transfer-induced electronic rearrangement of electronic configuration in Fe(8h) and Fe(4e) geometrical sites. These results are consistent with the previous model and help explain the saturation magnetization enhancement in the α-FeN system. © 2015 The Japan Society of Applied Physics.Charge transfer; Crystal structure; Electronic structure; Gallium arsenide; III-V semiconductors; Iron metallography; Nitrogen compounds; Photoelectrons; Photons; Saturation magnetization; Substrates; Textures; Thin films; X rays; Crystalline structure; Electronic configuration; Electronic hybridization; Fe thin films; Fe-n systems; Iron nitride thin films; Spectroscopic investigations; X-ray photoelectrons; Iron compoundsjournal article10.7567/jjap.54.0330022-s2.0-84924280366WOS:000352792200046
