摘要：

A novel process for in situ filling of long continuous FeNi nanowires into thin-walled carbon nanotubes (CNTs) is reported, which is achieved by simply using chlorine-contained benzene, C6H3Cl3, as the carbon precursor. The length of FeNi nanowires encapsulated in CNTs is up to similar to 4 mu m, which is increased by an order of magnitude compared with those of previous reports (lengths < 500 nm). Magnetic measurements on the sample show typical ferromagnetic properties with a Curie temperature (T-c) of 640 degrees C. Theoretical calculations show that this kind of materials is promising and can be used as an effective microwave absorber with a thinner coating layer. (C) 2007 Elsevier Ltd. All rights reserved.
