Magnetic x-ray microdiffraction uses the structural specificity of x-ray diffraction to probe complex magnetic structures at the length scales relevant to physical phenomena including domain dynamics and phase transitions. Conventional magnetic cryst

We report particle-hole pair excitations in a cuprate insulator in the intermediate regimes of momentum-transfers using high energy inelastic x-ray scattering. The excitation spectra show dispersive features near the Mott edge which shed light on the

We report on the development of a circularly polarized x-ray microprobe in the intermediate energy range from 5 to 10 keV. In this experiment linearly polarized synchrotron radiation was circularly polarized by means of a Bragg-diffracting diamond ph

Periodic intensity variations in the measured Compton profile anisotropies of ordinary ice Ih correspond to distances of 1.8 and 3.0 A, which are close to the hydrogen bond length and the nearest-neighbor O–O distance, respectively. We interpret th

We report inelastic x-ray scattering measurements of the energy, linewidth, and dispersion of the plasmon in metallic lithium ammonia at an electron concentration of $4\ifmmode\times\else\texttimes\fi{}{10}^{21}{e}^{\ensuremath{-}}/{\mathrm{cm}}^{3}$

We report resonant inelastic x-ray measurements of insulating La$_2$CuO$_4$ and Sr$_2$CuO$_2$Cl$_2$ taken with the incident energy tuned near the Cu K absorption edge. We show that the spectra are well described in a shakeup picture in 3rd order pert

Periodic intensity variations in the measured Compton profile anisotropies of ordinary ice $\mathrm{I}h$ correspond to distances of 1.72 and 2.85 \AA{}, which are close to the hydrogen bond length and the nearest-neighbor O-O distance, respectively.
