Neutron diffraction measurements were performed on single-crystal samples to study the nature of the exotic order phase of CeOs4Sb12 below the transition temperature 0.9 K. An antiferromagnetic ordering with propagation vector 4 = (1 0 0), and a tiny moment is determined as the magnetic ground state. Our neutron data provide direct evidence for a spin-density-wave (SDW) ground state as first proposed by Yogi et al.
