(Zn<sup>2+</sup>/Mg<sup>2+</sup>)[Fe<sup>3+</sup>]<sub>2</sub>O<sub>4</sub> spinel oxides can be refined as direct/fully inverted (respectively) spinels but considering cationic and anionic vacancies and/or interstitial atoms instead of a partial inversion rate of the A<sup>2+</sup> and B<sup>3+</sup> cations. The refinements results of the X-ray diffraction patterns and Mössbauer spectroscopy spectra are discussed and show the veracity of the new structural formalism.< Réduire
