“…Moreover, the appearance of this phase transition has been reported in the wide range of Sr content (0.1ϽxϽ0.15). 23,31 Recently, an interesting new concept, a so-called ''phase separation,'' has been proposed to explain the phase transition in manganite. 24,[32][33][34] This concept has been applied to the phase separation between a ferromagnetic domain and an antiferromagnetic domain.…”

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

“…Despite extensive investigations, controversy concerning the nature of the CO/OO in the FMI phase still remains at large. The characteristic superstructure reflections in the FMI phase were revealed earlier by a number of neutron and X-ray scattering experiments [1][2][3][4], which were usually interpreted in terms of the long-range charge ordering and associated lattice modulations. However, based on a recent resonant X-ray scattering (RXS) experiment [5], the earlier CO scenario was questioned since none of these superstructure reflections were found showing resonance behavior at the Mn K-edge, and then it was concluded that the OO is indeed the main characteristic of the FMI phase.…”
