説明:

(abstract)

The bulk band structure of an in situ prepared ferromagnetic Fe4⁢N thin film has been investigated using spin- and angle-resolved photoelectron spectroscopy with synchrotron radiation. It was observed that most of the bands near the Fermi level are of minority spin. The experimental results are well reproduced by first-principles calculations. Our orbital analysis of the band structure has revealed that the electron pocket near the Γ point is primarily attributed to the Fe 3⁢𝑑𝑥⁢𝑦 orbital of the Fe(II) site, while the electron pocket near the M point is associated with the Fe(II) 3⁢𝑑𝑧2 orbital. Our observation of real band structure in Fe4⁢N thin films could provide valuable insight into the properties of anisotropic magnetoresistance and anomalous Nernst effect.
