Abstract
A semi-conducting material being a non-oxide material or an already doped oxide material, wherein said material is doped with Manganese, Mn, and is ferromagnetic at least at one temperature in the range between room temperature and 500 K. Preferably, the Manganese doped material has a Manganese concentration at or below 5 at %.
