The crystal and magnetic structures of the charge ordered perovskite BiNiO3 have been studied at temperatures from 5 to 300 K using neutron diffraction. Rietveld analysis of the data shows that the structure remains triclinic (space group P 1 ¯ ) th

Continuous neutron sources such as reactors can deliver a very high time-averaged flux to the sample using a relatively wide band of wavelengths, while still retaining good resolution. For example, the D20 diffractometer at ILL Grenoble, the world's

In situ neutron diffraction at 0.9 s time resolution was used to reveal the reaction mechanism during the self-propagating high-temperature synthesis (SHS) of Ti3SiC2 from furnace-ignited stoichiometric 3Ti + SiC + C mixtures. The diffraction pattern

The crystal structure of barium oxalate hydrate, BaC2O4 · 3.5 H2O, was solved using both synchrotron X-ray powder diffraction data and neutron powder diffraction data of BaC2O4 · 3.5 D2O, and synchrotron X-ray single diffraction data, measured on a

In the system Mg1 − x Cu2 + x O3 the phase with x = 0, i.e. the compound MgCu2O3, does not exist. Neutron powder measurements and single crystal X-ray studies clearly show that the Mg lattice site is partially occupied by Cu2+ ions with typical val
