چکیده

Exploitation of X-ray circular polarized beams to study forbidden Bragg reflections and new information that could be obtained in these experiments are discussed. It is shown the intensities such can different for right- left-circular polarizations ( i.e. exhibiting dichroism) even dipole–dipole resonant transitions involved scattering process. This difference observed only crystals having no center inversion. Here, this approach used helicity-dependent diffraction copper metaborate CuB 2 O 4 single crystal, which non-centrosymmetric but achiral. Nonetheless, a strong dichroism has been hh 0 vicinity Cu K -edge. effect originate from dipolar atoms occupying 8( d ) Wyckoff position only.

Temperature-Dependent 1s2p Resonant Inelastic X‐ray Scattering of CoO

The temperature-dependent 1s2p resonant inelastic X-ray scattering (RIXS) spectra of CoO have been measured with 0.3 eV overall resolution, and the RIXS planes have been analyzed with multiplet calculations. The analysis of the high-resolution 1s2p RIXS plane allows a more detailed determination of the ground-state electronic structure, as compared to 1s X-ray absorption spectroscopy (XAS). The...

Resonant elastic soft x-ray scattering.

Resonant (elastic) soft x-ray scattering (RSXS) offers a unique element, site and valence specific probe to study spatial modulations of charge, spin and orbital degrees of freedom in solids on the nanoscopic length scale. It is not only used to investigate single-crystalline materials. This method also enables one to examine electronic ordering phenomena in thin films and to zoom into electron...

Resonant X-ray Scattering and Multiple Beam Diffraction in LaMnO3

Fig 1: The solid points give the location and shape of the (1 0 –4) resonant reflection in orthorhombic LaMnO3. Open circles display Mn Kα fluorescence from the same sample on a common energy scale. The vertical scale is arbitrary and the lines are guides to the eye. In conventional X-ray diffraction the beam scatters from all electrons in the unit cell, but in resonant diffraction at a forbidd...

Femtosecond dynamics of momentum-dependent magnetic excitations from resonant inelastic X-ray scattering in CaCu2O3.

Taking spinon excitations in the quantum antiferromagnet CaCu2O3 as an example, we demonstrate that femtosecond dynamics of magnetic electronic excitations can be probed by direct resonant inelastic x-ray scattering (RIXS). To this end, we isolate the contributions of single and double spin-flip excitations in experimental RIXS spectra, identify the physical mechanisms that cause them, and dete...
