Abstract

The change of magnetoresistance angular effects induced by strong electric fields has been studied in quasi-one-dimensional (Q1D) organic conductors. Numerical and experimental results on the electric field effect are presented. For each sheet-like Fermi surface, the interlayer electric field works as the effective magnetic field giving the same force, so that the phenomena depending on magnetic field orientations must show shift generally. We show that the Lebed resonances, the most basic angular effect in the Q1D system, show shift (or split) under electric fields, and demonstrate that the Fermi velocity can be estimated from these experiments. By combining the electric field effect, the magnetoresistance angular effects could be the more useful tool to study not only the Fermi surface topology but also the band dispersion in Q1D conductors.
