Abstract:   (10999 Views)

 Studies of phenomena such as charge, orbital and spin ordering in manganite has attracted much interest in recent years. These studies have been possible from an experimental point of view by the third generation synchrotron sources. X-ray with high flux density, tunable energy and polarization can be produced in synchrotron sources. Experiments have shown a resonant in peak intensity originating from charge and orbital ordering when the incident photon energy matches the manganese K-edge energy. In this paper we have calculated the scattering factor and intensity of charge and orbital ordering reflections on the Mn K-edge energy in Nd0.5Sr0.5MnO3 on the basis of its structure and the chosen model of charge and orbital ordering. The energy and azimuthal angle dependence of the peaks intensity have been investigated and compared with the experimental results.
