N2 - The polaron-ordered structure of La1-xSrxMnO3 (x≅1/8) has been reinvestigated to verify the previously proposed models. We found satellite reflections on the (0, k, l)ortho and (1, k′, l)ortho reciprocal planes. It has been shown that neither of the previously proposed models is completely consistent with the observed results. Based on theoretical consideration of interhole interactions in a perovskite-based structure, the experimental results are analyzed. A polaron ordered structure with unit cell size of (√2×√2×4)cubic has been proposed which is substantially consistent with the observed neutron-scattering pattern.
