## Description

- description: Interface band dispersion of a MgO(2 nm)/Fe(50 nm) heterostructure
    was detected by hard X-ray angle-resolved photoemission spectroscopy (HARPES)
    with the excitation photon energy of 3.29 keV by utilizing X-ray total reflection
    (TR).  By subtracting bulk-sensitive band dispersion of the buried Fe(001) obtained
    by HARPES in the non-TR condition from near-interface-sensitive Fe(001) band dispersion
    obtained by TR-HARPES, the band-folding of Fe and the O 2p -Fe 3d hybridization
    at the heterointerface were clearly unveiled. These results suggest that HARPES
    can probe not only bulk band but also buried interface band of heterojunctions.
