Abstract. Magnetite (Fe 3 O 4, ferrous–ferric oxide) is ubiquitous as the source of the magnetism of most biological magnetic systems.Although a cation-deficient form of it, maghemite (γ- Fe 2 O 3), and impurity-substituted magnetite (titanomagnetite) have on occasion been identified in biomagnetic systems, magnetite continues to be the primary magnetic source in biology.
