We have investigated the temperature dependence of the a and b′ direction conductivity in the spin-density wave phase of (TMTSF)2PF6 in the presence of a magnetic field (oriented perpendicular to the ab′ plane) and hydrostatic pressure. The band parameters are analyzed in the framework of the imperfect nesting model and the transfer integrals are deduced from the experiments. The variation of the thermal gap, Δth(B, p), is determined and it is compared to the theoretical expectations. Our results suggest that the strong influence of pressure and magnetic field on the a and b′ direction transport can be described in terms of band parameters without introducing anisotropy in the relaxation time.
