Orbital correlations in doped manganites

Orbital correlations in doped manganites

We review our recent X-ray scattering studies of charge and orbital order in doped manganites, with specific emphasis on the role of orbital correlations in Pr1-xCaxMnO3. For x=0.25, we find an orbital structure indistinguishable from the undoped structure and long-range orbital order at low tempera...
