Cation ordering and structural variations with temperature in MgAl2O4 spinel: An X-ray single-crystal study
TL;DR: In this paper, 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 single-crystal X-ray diffraction of quenched samples.
