Study and identification of the actinide electronic structure is complicated and crucial. Here the authors probe the hybridization between 5f to 6d orbitals in uranium compounds using X-ray magnetic circular dichroism near U-L3 edge through the dipol

Physical Review B. 101
The crystal lattice of ${\mathrm{Sr}}_{2}{\mathrm{IrO}}_{4}$ is investigated with synchrotron x-ray powder diffraction under hydrostatic pressures up to $P=43$ GPa and temperatures down to 20 K. The tetragonal unit cell is maintained over the whole i

We report on Mn K‐edge X‐ray absorption study, in plane and out of plane, of La0.7Sr0.3MnO3 films, epitaxially grown on a tensile substrate SrTiO3 by laser ablation. From Extended X‐ray Absorption Fine Structure in the film plane we observe a s

Equiatomic FePt thin films with fcc or L10 structure were studied by x-ray-absorption spectroscopy. The extended x-ray-absorption fine structure and x-ray-absorption near edge structure analysis, sensitive to the local structure and chemical order, s
