The DC conductivity of semiconducting Gd1/3Sr2/3FeO3 has been measured in the temperature range 77-300 K. The semiconducting phase is found to obey Mott's variable range hopping mechanism of the conduction. The parameters related to hopping conduction: viz., the characteristic temperature (T-0), localization length (alpha), hopping range (R), and hop energy (W) have been calculated.
