Abstract

We extend an earlier analysis of the electric conductivity of field-induced spin-density waves by including the higher-order terms in tb/ta where ta and tb are the electron-transfer integrals along the a and b axes, respectively. In the normal state the resulting conductivity tensor reproduces the result by Cooper et al. In the spin-density-wave states we predict an electric-field-dependent xx, but little electric field dependence for xy and yy associated with the Fröhlich conduction. We do not find the quantized Hall term within the single-gap approximation, although xy varies almost stepwise with the external magnetic field at low temperatures. The results are compared with some of the experiments on Bechgaard salts.
