Titanomagnetite

Titanomagnetite is a mineral containing oxides of titanium and iron, with the formula Fe²⁺(Fe³⁺,Ti)₂O₄. It is also known as titaniferous magnetite, mogensenite, Ti-magnetite, or titanian magnetite.^[1] It is part of the spinel group of minerals. The Curie temperature for titanomagnetite has been found to have a wide range of 200 to 580°C.^[2]
