Unusual Magic Angles Effects in Bechgaard Salts

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


We reviewed nontrivial angular magnetoresistance oscillations of Bechgaard salts, the representative quasi-one-dimensional conductors. The most frequently studied three compounds, (TMTSF)2ClO4, (TMTSF)2PF6, and (TMTSF)2ReO4, share the same background magnetoresistance and overall resonance structure regardless of external pressure and do not show dramatic change of metallic properties from one to another. However, weak periodic potential induced by anion ordering plays much more important role than it has been expected. It is responsible for the rich variety of Lebed resonances we have observed in various Bechgaard salts. The mechanism for the formation of a two-dimensional Fermi surface in (TMTSF)2FSO3 is unique and deserves further investigation.
