Arsenic uptake by gypsum and calcite: Modeling and probing by neutron and x-ray scattering
Alejandro Fernandez-Martinez, Gabriel J. Cuello, Gabriela Roman-Ross +4
Here we report on two structural studies performed on As-doped gypsum (CaSO4 2H2O) and calcite (CaCO3), using neutron (D20-ILL) and x-ray (ID11-ESRF) diffraction data and EXAFS (BM…
Dipolar excitations at the LIII x-ray absorption edges of the heavy rare earth metals
S. D. Brown, P. Strange, L. Bouchenoire +10
We report measured dipolar asymmetry ratios at the LIII edges of the heavy rare earth metals. The results are compared with a first principles calculation and excellent agreement i…
Direct observation of the high magnetic field effect on the Jahn-Teller state in TbVO4
C. Detlefs, F. Duc, Z. A. Kazei +6
We report the first direct observation of the influence of high magnetic fields on the Jahn-Teller (JT) transition in TbVO4. Contrary to spectroscopic and magnetic methods, X-ray d…
An x-ray resonant diffraction study of multiferroic DyMn2O5
R. A. Ewings, A. T. Boothroyd, D. F. McMorrow +3
X-ray resonant scattering has been used to measure the magnetic order of the Dy ions below 40K in multiferroic DyMnO. The magnetic order has a complex behaviour. There…
X-ray Resonant Scattering Study of the Order Parameters in Multiferroic TbMnO
D. Mannix, D. F. McMorrow, R. A. Ewings +7
We report on an extensive investigation of the multiferroic compound TbMnO. Non-resonant x-ray magnetic scattering (NRXMS) revealed a dominant -type domain. The temperature…
Influence of static Jahn-Teller distortion on the magnetic excitation spectrum of PrO2: A synchrotron x-ray and neutron inelastic scattering study
C. H. Webster, L. M. Helme, A. T. Boothroyd +6
A synchrotron x-ray diffraction study of the crystallographic structure of PrO2 in the Jahn-Teller distorted phase is reported. The distortion of the oxygen sublattice, which was p…
