Magnetite Article about magnetite by The Free Dictionary
A good conductor of electricity, magnetite is classified as a ferrimagnet owing to its magnetic properties. Its magnetization is determined by the difference in magnetic moments of the mineral’s two magnetic sublattices: (1) composed of Fe 2+ and Fe 3+ ions, located at the octahedral points, and (2) composed of Fe 3+ ions, located at the tetrahedral points.

Redox cycling of Fe(II) and Fe(III) in magnetite by Fe ...
2015-3-27 Iron acts as both a source and sink of electrons for microorganisms in the environment. Some anaerobic bacteria use oxidized Fe(III) as an electron acceptor, whereas phototrophic bacteria can use reduced Fe(II) as an electron donor. Byrne et al. show that the iron-bearing mineral magnetite, which contains both Fe(II) and Fe(III), can serve as both an electron acceptor and donor.
