説明
We have performed low-energy ultrahigh-resolution angle-resolved photoemission spectroscopy on CeSb to elucidate the bulk electronic structure responsible for the magnetic phase transition. By using a newly developed xenon-plasma discharge lamp, we clearly observed the splitting of Sb 5p3⁄2 and Ce 5d bands near the Fermi level as well as their strong hybridization below the Néel temperature (TN=16 K). We also revealed distinct differences in the band structure between the antiferropara- and antiferro-magnetic phases. These experimental results are discussed in terms of the p–f/p–d mixing effect, the exchange splitting, and the magnetic band-folding. The present result also explains the emergence of fine structures in the optical conductivity in the magnetic phase.
