We have investigated the charge and spin ordering in Nd 1 / 3 Sr 2 / 3 FeO 3 with neutron diffraction technique. This sample undergoes a charge ordering transition accompanying charge disproportionation of 2Fe 4 + ->Fe 3 + +Fe 5 + . We measured the superlattice reflections due to the charge and spin ordering, and confirmed that charges and spins order simultaneously at T C O =185K. The ordering pattern of charges and spins in this sample can be viewed as three-dimensional stripe order, and is compared with two-dimensional stripe order observed in other transition metal oxides.
