Diameter dependent magnetic and electronic properties of single-walled carbon nanotubes with Fe nanowires

We investigate the electronic and magnetic properties of single-walled carbon nanotubes (SWNTs) filled with Fe nanowires, based on the spin-polarized density functional theory. We find that in the stable structure, the Fe-filled (3, 3) and (5, 0) SWNTs exhibit semiconducting properties, and the magn...

Description
Summary:We investigate the electronic and magnetic properties of single-walled carbon nanotubes (SWNTs) filled with Fe nanowires, based on the spin-polarized density functional theory. We find that in the stable structure, the Fe-filled (3, 3) and (5, 0) SWNTs exhibit semiconducting properties, and the magnetic moment of Fe nanowires inside disappears. On the other hand, the Fe-filled (4, 4), (5, 5), (6, 6) and (6, 0) SWNTs, having larger radii, are metallic and exhibit ferromagnetic properties. The corresponding magnetic moment increases with increasing nanotube diameter. © 2005 The Japan Society of Applied Physics.
