    • Magnetite has a cubic inverse spinel structure with oxygen forming a face-centered-cubic close packing and Fe cations occupying interstitial tetrahedral sites and octahedral sites. Maghemite has a structure similar to that of magnetite, which only differs in that all or most of the Fe is in the trivalent state. Cation vacancies compensate for the oxidation of Fe(II) cations. Maghemite has a cubic unit cell in which each cell contains 32 O ions, 21-1/3) iron(III) ions, and (2, 2/3) vacancies. The cations are distributed over the eight tetrahedral and 16 octahedral sites, whereas the vacancies are confined to the octahedral sites. 50, the real chemical formula of magnetite and maghemite must be expressed as Fe24Fe8O32 and Fe 21 1/32- 2/3O32, respectively
