Abstract
A study of resonant-x-ray scattering in a charge-ordered perovskite manganese oxide Nd1/2Sr1/2MnO3 was performed. Dipole-resonant superlattice reflections originating from the orderings of the charge and orbital with Qcharge = (0,1,0) and Qorbital = (0,1/2,0) in the Pbnmsetting were observed. Sudden change in the intensity of the superlattice scattering at the transition temperature indicated a strong first-order phase transition. Characteristic dependence on the x-ray polarization was observed not only for orbital-order superlattice scattering but also for charge-order scattering. It should be closely related to the orbital-ordering type (d3x2-r2/d3y2-r2)or (dx2-z2/dy2-z2).
