Functional analysis of the magnetosome island in Magnetospirillum gryphiswaldense: the mamAB operon is sufficient for magnetite biomineralization [PDF]
, 2011 Bacterial magnetosomes are membrane-enveloped, nanometer-sized crystals of magnetite, which serve for magnetotactic navigation. All genes implicated in the synthesis of these organelles are located in a conserved genomic magnetosome island (MAI).

Magnetoresistance of Magnetite
Physica Status Solidi (a), 1972 The transversal magnetoresistance was studied in single crystals of natural magnetite for different temperatures between 300 and 77 °K and in fields up to 10 kG. For temperatures above the transition point, i.e. in the cubic phase, the magnetoresistance is positive and shows a maximum at 5 kG.
