Transition metal oxides have a long and distinguished history. They are familiar today as magnets, prized as materials for electronics, and aroused new interest. The fact that magnetite (Fe) was already known in the Greek era as a peculiar mineral is indicative of the long history of transition metal oxides as useful.
