Room temperature ferromagnetism in Mn-doped silicon carbide from first-principles calculations.

Abstract

Using density functional theory ab initio calculations, we study magnetic moments and ordering temperatures of Mn-doped 3C and 4H polytypes of silicon carbide (SiC) with the Mn impurities substituting at different lattice sites. For an improved accuracy of the Curie temperature (T(C)) and magnetic moment estimations, compared to earlier studies, the… (More)
