Abstract

Colossal magnetoresistive manganites are widely recognized as a typical example of spin, charge and orbital coupled systems. Recently, the anomalous X-ray scattering by utilizing the synchrotron radiation has been applied to manganites in order to directly observe the orbital order. We theoretically study the anomalous X-ray scattering as a probe to detect the orbital state in manganites. We identify an origin of the anisotropy of the atomic scattering factor in the orbital ordered state which causes the scattering in the orbital super lattice reflection point. By utilizing the derived general formula of the polarization dependence of the scattering intensity, we propose a method to determine several types of the orbital order. The recent development of the anomalous X-ray scattering experiments in orbital ordered manganites is briefly reviewed.
