Hematite - an overview | ScienceDirect Topics

For example, hematite is a semiconducting mineral [62], while goethite shows lower conductivity than hematite [63]. However, the conductivity of magnetite is significantly higher (×10 6) than hematite due to electron exchange between the Fe 2+ and Fe 3+ ions [64]. Hematite is weakly ferromagnetic above the Morin temperature (T M ≈ 260K).
