Magnetotransport properties of two-dimensional (2D) arrays of single-wall carbon nanotubes (SWCNTs) were investigated. The magnetoresistance (MR) in pulsed magnetic fields and the temperature dependence of the resistance of 2D arrays of SWCNTs were measured in the temperature range 1.8–300 K and in fields up to 9 T. The crossover between metallic and non-metallic temperature dependence of the resistance was observed at T ≈ 125 K. At low temperature, positive MR was observed with decreasing amplitude with the increase of temperature.
