Dynamical Effects in Resonant X-Ray Diffraction

Physical Review Letters, 2016
Using resonant magnetic diffraction at the Ni L_{2,3} edge in a LaNiO_{3} superlattice, we show that dynamical effects beyond the standard kinematic approximation can drastically modify the resonant scattering cross section. In particular, the combination of extinction and refraction convert maxima to minima in the azimuthal-angle dependence of the ...

The covariant approach in the dynamic theory of resonant X-ray diffraction

Moscow University Physics Bulletin (English Translation of Vestnik Moskovskogo Universiteta, Fizika), 2013
The main equations of the dynamic theory of X-ray synchrotron radiation resonant diffraction were obtained based on direct (coordinate-free) methods of tensor calculus.

On the resonant diffraction of X-rays

Il Nuovo Cimento D, 1993
Data on the absorption by a crystalline powder of Ge and on the intensities diffracted by the (111) planes of a perfect Ge crystal were collected in the laboratory at frequencies of the incident X-ray beam close to the photoelectric resonance for theK electrons of Ge.

Effects of dispersion and absorption in resonant Bragg diffraction of x-rays

Journal of Physics: Condensed Matter, 2014
Resonant diffraction of x-rays by crystals with anisotropic optical properties is investigated theoretically, to assess how the intensity of a Bragg spot is influenced by effects related to dispersion (birefringence) and absorption (dichroism). Starting from an exact but opaque expression, simple analytic results are found to expose how intensity ...

Resonant x-ray diffraction: multipole interpretation

Journal of Physics D: Applied Physics, 2012
Abstract The aim of this work is to provide a critical review of the multipole interpretation of resonant x-ray diffraction. After a brief historical introduction, we focus on the general formalism of electromagnetic multipole expansion in condensed matter.
