S. Ishihara et S. Maekawa, Polarization dependence of anomalous x-ray scattering in orbital-ordered manganites, PHYS REV B, 58(20), 1998, pp. 13442-13451
In order to determine types of the orbital ordering in manganites, we study
theoretically the polarization dependence of the anomalous x-ray scatterin
g, which is caused by the anisotropy of the scattering factor. The general
formula of the scattering intensity in the experimental optical system is d
erived and the atomic scattering factor is calculated in the microscopic el
ectronic model. By using the results, the x-ray scattering intensity in sev
eral types of the orbital ordering is numerically calculated as a function
of azimuthal and analyzer angles. [S0163-1829(98)09443-0].
