dc.description.abstractThe structures of eight members of the series Sr1-xCexMnO3 with 0.075≤x≤0.4 have been established using synchrotron X-ray powder diffraction. Unusual peak broadening due to domainwall scattering is observed near the composition-induced first-order cubic–tetragonal transition. The temperature dependence of the structures for three examples x = 0.1, 0.2 and 0.35 is described. For the x = 0.1 and 0.35 samples evidence for a first-order loss of the orbital ordering associated with a cooperative Jahn–Teller distortion is presented. The onset of the orbitally disordered state is accompanied by a discontinuous reduction in cell volume. © 2008, Elsevier Ltd.en_AU
