Thermally activated conductivity at integer Landau-level filling factors in the Q2D organic metal β″-(BEDT-TTF)2SF5CH2CF2SO 3 was observed for the first time. The activation energies deduced from the conductivity showed good agreement with the Landau-level spacings once broadening is taken into consideration.
