Fe3O4 is Spinel-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are three inequivalent Fe+2.67+ sites. In the first Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six equivalent FeO4 tetrahedra and edges with six FeO6 octahedra.
Magnetite is an important ore of iron. Well formed crystals are popular among mineral collectors, and the magnetic Lodestone variety is frequently sold in hobby shops to amateur collectors. Magnetite is also of significant interest to the science community due to its strong magnetic properties.

Nov 30, 2014· This high magnetization value probably arises from the surface spin disorder, which can be aligned in the direction of the applied magnetic field more easily than core spins. Accordingly, we conjecture that high magnetic moment of the nanoparticles is a consequence of nanoparticle shell.

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth.
