STRUCTURAL DISTORTIONS IN THE PARAMAGNETIC INSULATING PHASE OF LA(0.7)CA(0.3)MNO(3). [electronic resource]
We report x-ray scattering studies of polarons and tilt ordering in the high-temperature, paramagnetic insulating phase of La{sub 0.7}Ca{sub 0.3}MnO₃. The temperature dependence of scattering due to individual and correlated polarons was measured, and the latter was found to disappear at ∼400 K. The...

| 520 | 3 | |a We report x-ray scattering studies of polarons and tilt ordering in the high-temperature, paramagnetic insulating phase of La{sub 0.7}Ca{sub 0.3}MnO₃. The temperature dependence of scattering due to individual and correlated polarons was measured, and the latter was found to disappear at ∼400 K. The scattering due to tilt ordering, which was observed by tuning the incident photon energy near the La L₁ edge, was also measured as a function of temperature. The destruction of tilt ordering at ∼690 K is believed to be associated with the orthorhombic-rhombohedral structural transition. | |
