The coupling between spins and charge disproportionation states has been investigated in theoxide with neutron powder diffraction. This-site layer ordered triple perovskiteundergoes charge disproportionation on cooling and shows two different charge ordering patterns. At 230 K,disproportionates into a 2:1 ratio of, which order in a layered manner along thedirection of the pseudocubic unit cell. At lower temperatures, the charge ordering pattern changes to a layered arrangement along thedirection. Neutron powder diffraction data show that in the intermediate temperature range () the spins order into a cycloidal structure on theplane for thecations while thecations remain paramagnetic. For the lowest temperature range (), the spin structure follows the charge ordering and evolves to alayered magnetic structure.
