Re-examination of charge and orbital ordering in lightly doped La1−Sr MnO3 by X-ray scattering

Abstract We report on the new synchrotron X-ray scattering results from the re-investigation of charge and orbital ordering in lightly doped La 1− x Sr x MnO 3 . The resonant X-ray scattering from forbidden Bragg reflections was observed not only in the ferromagnetic insulating phase, but also in strongly Jahn–Teller distorted regime. Some of characteristic superstructure reflections were also found to show a clear resonant behavior at the Mn K absorption edge. It can be argued that the exact pattern of charge and orbital ordering should be much more complicated.
