Abstract
The electronic structures, magnetic properties and optical properties of (Fe, Ni) co-doped 3C-SiC system are systematically studied based on the first principles calculation. The results show that Fe single doped, Ni single doped, and (Fe, Ni) co-doped system all induce magnetism. The most stable (Fe, Ni) co-doped systems is determined by calculating the magnetic coupling energies of ten different configuration. The (Fe, Ni) co-doped systems indicated that have a higher Curie temperature and the (1, 7) configuration significantly improves FM stability compared to other configurations. In addition, the results of the optical properties of (Fe, Ni) co-doped 3C-SiC exist absorption in the entire infrared, visible, and ultraviolet light regions, which has a substantial change compared with the undoped system. An effective way is comfirmed to improve the magnetic and optical performance of 3C-SiC.
