• In order to investigate the electronic structures in the magnetically ordered states of CeSb, we measured the optical reflectivity and the magnetic circular dichroism in the infrared region at low temperatures under a magnetic fled. The optical conductivity spectrum, as well as the reflectivity spectrum, varies with the changing of temperature and magnetic field due to the magnetic phase transition. The optical spectrum originates from the absorption from the top of the Sb 5p band to the bottom of the Ce 5d band. The spectra in the ordered states cannot be explained only by the energy band folding due to the appearance of the periodic magnetic structure. It was found that the Sb 5p band is strongly modified by the appearance of the Ce 4f Γ_8 state in the ordered state. The Sb 5p-Ce 4f mixing effect is considered to play an important role in the magnetic phase transition.
