摘要：
The magnetic properties of Fe-alloy-capped carbon nanotube synthesized by chemical vapor deposition have been demonstrated in magnetic force microscopy (MFM) using a metal current ring, which produces well-defined magnetic field. The dipole and monopole moments of the Fe-capped carbon nanotube are measured to be 1.9 x 10(-12) emu and 2.6 x 10(-8) emu/cm, respectively. These values are 2 times and 4 times lager than those of the Ni-capped carbon nanotube, respectively. The result suggests that the Fe-capped carbon nanotubes are more suitable for MFM tips.
