In this paper, the magnetic and electronic properties of single aluminum and silicon atom added to small carbon clusters (CnX; X = Al, Si; n = 2–10) are studied in the framework of generalized-gradient approximation using density functional theory. The calculations were performed for linear, two dimensional and three dimensional clusters based on full-potential local-orbital (FPLO) method. The total energies, HOMO–LUMO energy gap and total magnetic moments of the most stable structures are presented in this work. The calculations show that CnSi clusters have more stability compared to CnAl clusters. In addition, our magnetic calculations were shown that the CnAl isomers are magnetic objects whereas CnSi clusters are nonmagnetic objects.
