Anomalous x-ray diffraction studies show that the charge ordering in $\alpha^\prime$-NaV$_2$O$_5$ is of zig-zag type in all vanadium ladders. We have found that there are two models of the stacking of layers along \emph{c-}direction, each of them consisting of 2 degenerated patterns, and that the experimental data is well reproduced if the 2 patterns appears simultaneously. We believe that the low temperature structure contains stacking faults separating regions corresponding to the four…

Resonant x-ray scattering experiments on electronic orderings inNdNiO3single crystals

We have carried out resonant x-ray scattering experiments on ${\mathrm{NdNiO}}_{3}$ single crystals aiming at the observation of a predicted orbital ordering that may explain the presence of an

Temperature dependence of the crystal structure and charge ordering in Yb 4 As 3

Resonant and nonresonant x-ray scattering, combined with x-ray absorption data, are presented on ${\mathrm{Yb}}_{4}{\mathrm{As}}_{3}$. The nonresonant data allow a detailed determination of the

Low-temperature structure of magnetite studied using resonant x-ray scattering

We propose a model for the Fe atomic displacements in the low-temperature phase of magnetite Fe3O4 , based on the analysis of the photon energy dependence of the scattered intensity of selected


We review recent synchrotron diffraction studies of NaV2O5. The resonant X-ray scattering performed on a monoclinically-split single domain of NaV2O5 shows a critically enhanced contrast between V4+

Low-temperature superstructure and charge-ordering effect in η-Na 1.286 V 2 O 5

In this work, we report on x-ray diffraction, electron spin resonance, and magnetic susceptibility measurements performed on η-Na 1 . 2 8 6 V 2 O 5 . The x-ray data clearly reveal the existence,

X-ray resonant scattering of (004n+2) forbidden reflections in spinel ferrites

The origin of the x-ray resonant scattering of (002) and (006) forbidden reflections in the spinel ferrites has been investigated. Resonant features were previously observed in Fe{sub 3}O{sub 4} at

Structural origin for the dipole x-ray resonant scattering in the low temperature phase of Nd0.5Sr0.5MnO3 manganite

We have investigated the low temperature phase of a Nd0.5Sr0.5MnO3 single crystal by x-ray resonant scattering at the Mn K-edge of the (3 0 0), (0 3 0) and (0 5/2 0) reflections. Strong resonances

Local structure of magnetite and zirconates of perovskite type by resonant diffraction and X-ray absorption

This thesis concerns the study of two classes of the oxides by the resonant x-ray diffraction and X-ray absorption spectroscopy for the magnetite and perovskites. The electronic structure of Fe3O4

Electronic structure alpha '-NaV2O5: Wave-function-based embedded-cluster calculations

Results of ab initio embedded-cluster calculations indicate that the doublet ground state of the V-O-R-V rung originates from a V 3d(xy)(1)-O(R)2p(y)(1)-V 3d(xy)(1) configuration. In the high

Anomalous scattering in structural chemistry and biology

The uses of X-ray anomalous scattering in crystal structure analysis have undergone a major expansion due to the refinement and ease of availability of the necessary X-ray instrumentation and
