摘要：
In this research work, magnetic multi-walled carbon nanotube (MWCNTs) nanocomposites have been created by the assembly of Mn-Co-Ti-substituted barium ferrite nanoparticles onto the surface of MWCNTs. X-ray diffraction (XRD) and transmission electron microscopy (TEM) were used to demonstrate the successful attachment of ferrite nanoparticles to MWCNTs. Vibrating sample magnetometry (VSM) confirmed the relatively strong dependence of saturation magnetization on the volume percentage of MWCNTs. Microwave absorption of the MWCNTs/doped barium ferrite (BaM) nanocomposites is evidently enhanced compared to that of pure MWCNTs and ferrite nanoparticles. The maximum reflection loss increased significantly with an increase in volume percentage of MWCNTs in nanocomposites. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3551727]
