• The transverse magnetoresistance of the Bechgaard salt (TMTSF)2PF6 has been measured for various pressures, with the field up to 24 T parallel to the lowest-conductivity direction c*. A quadratic behavior is observed in the magnetic-field dependence of the spin-density-wave (SDW) transition temperature TSDW. With increasing pressure, TSDW decreases and the coefficient of the quadratic term increases. These results are consistent with the prediction of the mean-field theory based on the nesting of the quasi-one-dimensional Fermi surface. Using a mean-field theory, TSDW for the perfect nesting case is estimated as about 16 K. This means that even at ambient pressure where TSDW is 12 K, the SDW phase of (TMTSF)2PF6 is substantially suppressed by the two dimensionality of the system.
