The crystal structure of magnesium aluminate is conventionally described within a symmetry corresponding to the centrosymmetrical space group Fd3m but this has created difficulties for the interpretation of many of its physical properties. Therefore, extensive X-ray diffraction intensity data have been collected from a small spherical synthetic single crystal and used for a structure parameter refinement assuming F4̅3m symmetry as proposed by Grimes (Phil. Mag. 26, 1217‒1226 (1972)), and also…

Does magnetite lack a centre of symmetry

Doubts concerning the conventionally assumed centrosymmetry of the cubic crystal structure of spinel ferrites, including magnetite, have existed for many years, chiefly because dielectric constants

Spinel and Spinels

Crystal chemistry of a highly disordered Mg-Al natural spinel

SummaryA Mg-Al spinel from a xenolith found in the Sacrofano volcanic area (Latium, Italy) was investigated by X-ray single crystal diffraction and electron microprobe. Its main structural parameters

Cation ordering and structural variations with temperature in MgAl2O4 spinel: An X-ray single-crystal study

Abstract The equilibrium distribution of Mg and Al between the tetrahedral and octahedral sites of a flux grown, stoichiometric MgAl2O4 spinel was investigated between 600 and 1100 °C by

Cation distribution in natural Zn-aluminate spinels

Abstract The intracrystalline cation distributions in fourteen natural Zn-aluminate spinels were determined by means of X-ray single-crystal structural refinement, supported for some samples by

The crystal structure and cation distributions in the spinels MgCr204, ZnCr20~, Fe30~ and a suite of ZnA1204 samples annealed at 900 to 1400 ~ C and then rapidly quenched, have been determined by

Ab Initio Thermodynamic and Structural Studies of Cationic Disordered MgAl2O4 Spinel

Structural and thermodynamic properties of disordered MgAl2O4 spinel are calculated by DFT with plane-wave basis set and pseudopotentials. Several configurations are considered to average each

Inversion in Mg1-xNixAl2O4 Spinel: New Insight into Local Structure.

Based on neutron total scattering experiments, it is determined that the local structure of Mg1-xNixAl2O4 spinel cannot be understood as simply being due to cation disorder, rather, cation inversion creates a local tetragonal symmetry that extends over sub-nanometer domains.

Structure of Spinel

This paper reviews the crystal structure of compounds with the general formula AB 2 X 4 , which crystallize with the same atomic structure as the mineral spinel, MgAl 2 O 4 . Three degrees of freedom



Space group of the spinel structure: A neutron diffraction study of MgAl2O4

It has been suggested that the crystal structure of cubic spinel compounds should be referred to the non-centrosymmetric space group F43m instead of the customary space group Fd3m. The need for the

'Off-centre' ions in compounds with spinel structure

Abstract Experimental evidence from several sources suggests that, contrary to general belief, the crystal structure of cubic spinels is not satisfactorily referred to the space group Fd3m. The

Further discussion on the space group of spinel

Electron-diffraction evidence that spinel has a lower space group than Fd3m is reviewed, and it is reaffirmed that the presence of (200), (420), etc reflections in (001) zone axis diffraction

X-ray diffraction studies of the spinel series Mg(CrxAl2-x)O4 I. Lattice parameters and structure

Eight polycrystalline samples of the spinel series Mg(CrxAl2-x) O4 with 0<or=x<or=2 have been prepared. The lattice parameters have been determined by the centroid method, and the variation with

On the space group of spinel, MgAl2O4

The controversial space-group problem of spinel, MgAl2O4, whether it is Fd3m or F{\bar 4}3m, was studied by electron diffraction. It was confirmed that the appearance of 'forbidden reflections' such

Multiple diffraction in spinel and the space‐group ambiguity

The elimination of the ambiguity in the assignment of a space group for the spinel structure depends upon the detection of very weak `forbidden reflexions' in the presence of substantial multiple
