Magnetit – Wikipedia

Als Titanomagnetit (englisch auch Titaniferous Magnetite werden die Mischkristalle der Reihe Magnetit (Fe 3 O 4) und Ulvöspinell (Fe 2 TiO 4) bezeichnet. Die Mischkristallformel wird allgemein mit Fe 2+ (Fe 3+,Ti) 2 O 4 (genauer auch mit xFe 2 TiO 4 ·(1-x)Fe 3 O 4). Diese Mischreihe ist nur oberhalb von etwa 600 °C vollständig.

Magnetite (fe3o4) - an overview | ScienceDirect Topics

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 have been investigated in some detail.
