Extract

We discuss recent low temperature results on the magnetoresistance of (TMTSF)2C104 in the low field metallic and the moderate field FISDW phases. From constant field rotations in a plane perpendicular to the highest conducting a-axis, we observe oscillatory resistance behavior along certain orientations at al. fields measured. While at odds with usual considerations of resistance anisotropy due to the crystal structure, this feature may be consistent with the recent predictions of Lebed and Bak[1,2], wherein the oscillatory electron trajectories along the b* and c* directions become commensurate near particular “magic” orientations in the magnetic field. We compare our preliminary data with the Lebed-Bak model, finding some qualitative agreement.
