Variation as a function of temperature of isotropic atomic displacement parameters of Cu/Mg (blue diamonds), Cr (green diamonds) and O (red diamonds) atoms for spinel samples of different compositions across the MgxCu1 − xCr2O4 join. (a) CuCr2O4; (b) Mg0.10Cu0.90Cr2O4; (c) Mg0.18Cu0.82Cr2O4; (d) Mg0.46Cu0.54Cr2O4. |
