Orthorhombic goethite (αFeOOH) is the most important of these minerals and is a common constituent of soils and sediments. Goethite is antiferromagnetic with a Néel temperature of 120°C, but it has a weak superimposed parasitic ferromagnetism that probably arises from a defect moment as in hematite, with which it is often intergrown.
