Magnetic properties of Fe nanoparticles trapped at the tips of the aligned carbon nanotubes
نویسندگان
چکیده
The magnetic properties of iron nanoparticles partially encapsulated at the tips of aligned carbon nanotubes have been studied. The carbon nanotube wall not only protects the metallic particles from oxidization, but also reduces the inter-particle dipolar interaction by non-magnetic separation. Magnetic characterizations performed in the temperature range of 5–350K with magnetic field up to 3T show that these carbon-nanotube-supported iron particles are good candidates for high-density magnetic recording media. # 2001 Elsevier Science B.V.

Radar absorbing materials, i.e. magnetite (Fe3O4) coated carbon fibers (MCCFs) were fabricated by electro-deposition technique. Black-colored single spinel phase Fe3O4 nanoparticles was easily synthesized by hydrothermal method using reduction of a Fe (III) - Triethanolamine complex in an aqueous alkaline solution at 60-80 ◦C. Uniform and compact Fe3O4 films were fabricated on nitric acid treat...
متن کاملEvaluation of catalyst ball-milling process on growth and diameter of carbon nanotubes on iron nanoparticles
In this study, we describe the growth of carbon nanotubes on commercial iron nanoparticles without carbon shell (Fe (nm), size 2O3 and Fe* (nm)/MgO) was carried out by mixing commercial Fe* nanoparticles (as catalyst) with Al2O3 and MgO powders (as supports)by using ball-milling method. The results show in spite of the fact that ball-milling process can have neg...
