Abstract

The magnetoresistance of the quasi-one-dimensional organic conductor (TMTSF)2PF6 is studied under a hydrostatic pressure of about 0.8 GPa in magnetic fields up to 12 T perpendicular to the conducting a-b planes in the temperature range of 5 to 35 K. Both in the best conducting a and second best conducting b directions, the magnetoresistance follows a power law ΔR/R = (B/B0)3/2. The a-b plane anisotropy is field independent. The scaling field B0 follows an exponential temperature dependence B0∝exp(T/T0) with T0 = 10 K. These findings are discussed in terms of recent theories of the magnetoresistance in (TMTSF)2PF6.
