Abstract
In the present work the transport properties of mesoporous mesophase carbon (MMC) powder have been investigated in wide temperature and magnetic field ranges. It has been found that in the range 1.5–42 K the temperature dependence of the resistivity of this material can be described by Efros–Shklovskii variable range hopping law. In the same temperature range the magnetoresistance is positive but does not fit the exponential dependence expected in the hopping regime.
