Synchrotron x-ray scattering of magnetic and electronic structure of UN and epitaxial films Open
We examine the magnetic ordering of UN and of a closely related nitride,\nU2N3, by preparing thin epitaxial films and using synchrotron x-ray techniques.\nThe magnetic configuration and subsequent coupling to the lattice are key\nfeatures …

Role of the orbital moment in a series of isostructural weak ferromagnets Open
The orbital contribution to the magnetic moment of the transition-metal ion in the isostructural weak ferromagnets ACO(3) (A = Mn,Co,Ni) and FeBO3 was investigated by a combination of first-principles calculations, nonresonant x-ray magnet…

Persistence of antiferromagnetic order upon La substitution in the Mott insulator Open
The chemical and magnetic structures of the series of compounds Ca2−xLaxRuO4 [x = 0, 0.05(1), 0.07(1), 0.12(1)] have been investigated using neutron diffraction and resonant elastic x-ray scattering. Upon La doping, the low-temperature S-P…

Proton configurations in the hydrogen bonds ofas seen by resonant x-ray diffraction Open
KH2PO4 (KDP) belongs to the class of hydrogen-bonded ferroelectrics, whose\nparaelectric to ferroelectric phase transition is driven by the ordering of the\nprotons in the hydrogen bonds. We demonstrate that forbidden reflections of\nKDP, …
