Magnetic semiconductors

Engineering ferromagnetism

Semiconductors that exhibit room-temperature ferromagnetism are central to the development of semiconductor spintronics. Manganese-doped chalcopyrites are a promising class of such materials, but their success will depend on our ability to understand and optimize their behaviour. First-principles materials design could provide a way to achieve these goals.
