Using first principles calculations based on KKR Korringa Kohn Rostoker method related to the Coherent Potential Approximation (CPA), we have investigated the magnetic properties of silicon-carbide doped by transition metals (TM). In addition, for some concentrations of the TM elements (Mn, Cr), we have found that the ferromagnetic states appear in the 3C–Si1−x−yMnxCryC system. Moreover, the total magnetic moment of 3C–Si1−xTMxC increases with increasing TM (TM = Mn or Cr) concentrations. As well, our results indicate that the Curie temperature of 3C–Si1−xTMxC and 3C–Si1−x−yMnxCryC increases with increasing transition metal concentration. Finally, we have found that the double exchange interaction between Cr and Mn is the mechanism responsible for the ferromagnetism in 3C–Si1−xTMxC and 3C–Si1−x−yMnxCryC systems. © 2017 The Physical Society of the Republic of China (Taiwan)
