Crystal structure of synthetic Mg3Cr2Si3O12, the high-pressure Cr end-member of the knorringite-pyrope garnet series
Amélie Juhin, Guillaume Morin, Eric Elkaim +3
Knorringite, the Cr-end-member of the pyrope garnet series (Nixon et al. 1968), often occur in high proportions in kimberlite garnets and is thus used for tracing high-pressure dee…
X-ray Linear Dichroism in cubic compounds: the case of Cr3+ in MgAl2O4
Amélie Juhin, Christian Brouder, Marie-Anne Arrio +7
The angular dependence (x-ray linear dichroism) of the Cr K pre-edge in MgAl2O4:Cr3+ spinel is measured by means of x-ray absorption near edge structure spectroscopy (XANES) and co…
Intermediate range order in (Fe,Al) silicate network glasses: a neutron diffraction and EPSR modeling investigation
Coralie Weigel, Laurent Cormier, Georges Calas +2
The local structural environment and the spatial distribution of iron and aluminum ions in sodosilicate glasses with composition NaFexAl1-xSi2O6 (x = 1, 0.8, 0.5 and 0) is studied…
Nature and distribution of iron sites in a sodium silicate glass investigated by neutron diffraction and EPSR simulation
Coralie Weigel, L. Cormier, Georges Calas +2
The short and medium range structure of a NaFeSi2O6 (NFS) glass has been investigated by high-resolution neutron diffraction with Fe isotopic substitution, combined with Empirical…
Structural relaxation around substitutional Cr3+ in pyrope garnet
Amélie Juhin, Georges Calas, Delphine Cabaret +2
The structural environment of substitutional Cr3+ ion in a natural pyrope Mg3Al2Si3O12 has been investigated by Cr K-edge Extended X-ray Absorption Fine Structure (EXAFS) and X-ray…
XANES determination of chromium oxidation states in glasses: comparison with optical absorption spectroscopy
Olivier Villain, Georges Calas, Laurence Galoisy +2
The oxidation state of chromium in glasses melted in an air atmosphere with and without refining agents was investigated by Cr K-edge X-ray Absorption Near-Edge Structure (XANES) a…
