Abstract

Neutron diffraction experiment was performed to investigate a nature of the ordered phase below 0.9 K of the filled skutterudite Kondo semiconductor CeOs₄ Sb₁₂. We observed antiferromagnetic ordering with a tiny magnetic moment of around 0.03 μ_B/f.u. characterized by the wave vector q=(1 0 0). The magnetic ordered state can be interpreted as a spin density wave formation due to the nesting of the small Fermi surface within the hybridization gap.
