abstract
High-resolution low-temperature angle-resolved photoemission spectroscopy of Fe(1 1 0) single crystal has been done to evaluate many-body interactions on the quasi-particles at the Fermi level. A kink structure in the minority-spin band (B↓) on the Fermi surface (FS) around the Γ point has been clearly observed at the binding energy of ∼40 meV, but it is absent for the majority-spin band (B↑) on the FS around the Γ point. Additional spectral feature has been observed for B↑, indicating a coexistence of a surface resonance state. By the analyzes of the imaginary part of the self-energy, we have confirmed that the kink structure is derived from the electron-phonon interaction.
