Abstract
Submicron ferromagnets, of selected size and spacing, are introduced into semiconductor by means of ion implantation and subsequent heat treatments. The resulting semiconductor contains ferromagnets at high density and which exhibit Curie temperatures exceeding room temperature. The semiconductor retains its intrinsic physical properties, such as optical and transport properties, after incorporation of the ferromagnetic nanostructures.
