摘要

In this paper, we report the induced magnetization in metallic and semiconducting SiCNTs on the adsorption of transition metals. The resultant adsorbed SiCNTs structures showed half-metal-ferromagnetic and ferromagnetic behaviour verifying the induced magnetization. The spin-density of states and bandstructure have also been studied, confirming the induced magnetic behaviour. The strength of the induced ferromagnetic behaviour is varied with the various transition metals and is then related to the calculated magnetic moment in the adsorbed structure. The Cr adsorbed (8,0) SiCNT indicated strong half- metal-ferromagnetic behaviour with a magnetic moment of 5.4 μ_B. Only Cu-adsorbed (6,0) metallic SiCNT showed ferromagnetic behaviour among all the simulated structures indicating the impact of transition metal on the SiCNT structures. These promising results will be helpful in designing of devices like spin-valves, MTJs, and MRAMs in the field of spintronics.
