Perpendicular magnetic anisotropy (PMA) is induced at the Fe/Au(111) interface. We examine the origin of PMA using synchrotron radiation Mossbauer spectroscopy. From the spectral analysis, we detected the interfacial proximity effect which modulate the valence-band electronic structure of deposited Fe. Further, we explain that Mossbauer spectroscopy is also a powerful technique to investigate the interfacial electronic and magnetic properties.
