Abstract
This paper focuses on the study of single-walled carbon nanotubes (SWNTs) filled with magnetic Fe nanoparticles. The magnetic properties of Fe-filled SWNTs are measured at various temperatures, and the results indicate that they exhibit a ferromagnetic characteristic at room temperature and superparamagnetic properties at low temperatures. In addition, the electrical transport properties of Fe-filled SWNTs are examined, and the results demonstrate that their electronic properties depend on the filling level of the encapsulated Fe particles. It is found that Fe-filled SWNTs can exhibit high-performance unipolar n-type semiconducting characteristics at high filling levels and p-n junction diode behavior at low filling levels.
