    Abstract

    We have performed magnetoresistance measurements along the least conducting c direction in (TMTSF)2ClO4 under 6 kbar pressure while the magnetic field was rotated in the bc plane. Here 6 kbar is sufficient to suppress the (0,1/2,0) ordering transition observed at ambient pressure. Comparison with similar experiments on anion-ordered (TMTSF)2ClO4 and with (TMTSF)2PF6 allow the following conclusions: The periodicity is ill defined in the b but not the c direction in the presence of anion disorder, the disorder has a small to negligible effect on the scattering rate along c, and the anion ordering is not responsible for previously observed differences in angular-dependent magnetoresistance in these sister salts.
