Magnetite (Fe 3 O 4), which has an inverse spinel structure (Fig. 5 Fig. 6), has a high conductivity as a result of electrons jumping between the octahedrally coordinated Fe 2+ ions and the Fe 3+ ions (octahedrally and tetrahedrally coordinated). For this reason magnetite has been the subject of a number of studies by STM. All three basal planes
