摘要：

Temperature dependencies of the resistance R(T) and magnetoresistance (MR) of single-wall carbon nanotube (SWCNT) fibers have been investigated. R(T) shows negative dR/dT at 4.2-300 K and can be well fitted by Mott's law for 3-D variable range hopping (VRH) up to similar to 80 K. The negative MR at low fields with a positive upturn observed in the system can be explained by Shklovskii-Efros and Sivan models of MR for hopping conductivity.
