Abstract
In framework of some extension of the quasi-classical Boltzmann
kinetic equation, we show that a moderately strong electric field
splits the so-called Lee-Naughton-Lebed's magnetoconductivity
maxima in a layered quasi-one-dimensional conductor, if we use
some reasonable approximation to the equation. By means of the
above mentioned approximation, we obtain analytical formula for
conductivity in high magnetic and moderately high electric fields
and show that it coincides with the hypothetical formula as well
as adequately describes the pioneering experimental data by
Kobayashi et al. [K. Kobayashi, M. Saito, E. Omichi, and T. Osada,
