Abstract

We have discovered a new type of angular dependent magnetotransport which permits the measurement of the Fermi surface parameters of quasi-one-dimensional metals. Resistance measurements of (TMTSF)2ClO4 in the c (least conducting) direction show pronounced resonances when the field is rotated in the a-c plane near the a axis. At these resonances each electron trajectory across the warped Fermi surface sheets has an average velocity along c approaching zero. The resonance angles are determined by the bandwidths and allow us, for example, to extract tb. For (TMTSF)2ClO4 in the anion ordered state, we measure tb=0.012±0.001 eV.
