Abstract
Lebed resonance phenomenon which manifests sharp resistance minima at angles where the magnetic field imposes electrons a periodic motion on the Fermi surface, is readily observed in most of Bechgaard salts such as (TMTSF) 2ClO4, (TMTSF)2PF6, (TMTSF) 2ReO4. On the other hand, another type of oscillatory behavior, observed when the magnetic field rotates from the most conducting direction towards the least conducting direction, in the acplane, is found to vary much from one compound to another, having been clearly observed only in (TMTSF)2ClO4. We have performed a systematic study of both the bc- and ac-rotation measurements and report that the ac-plane resonances are also omnipresent and universal in all the three compounds. Difference among compounds, notably the strength of the coherence peak may be used to account for the evolution of coherence from one compound to another. © 2006 IOP Publishing Ltd.
