We report resonant x-ray scattering studies of charge and orbital order in Prl−x
MnO3 with x=0.4 and 0.5. Below the ordering temperature, T
=245 K, the charge and orbital order intensities follow the same temperature dependence, including an increase at the antiferromagnetic ordering temperature, TN
. High resolution measurements reveal, however, that long range orbital order is never achieved. Rather, an orbital domain state is formed. Above T
, the charge order fluctuations are more highly correlated than the orbital fluctuations. We conclude that the charge order drives the orbital order at the transition.
