STATIC SKIN EFFECT AT HIGH-CURRENT DENSITIES

The nonlinear effects in the conductivity of metals and intrinsic semiconductors placed into a homogeneous magnetic field H(o) are investigated under the conditions of the static skin effect. The electric current distribution and the intrinsic magnetic field of the current H(j) in the sample are obtained by the asymptotic solution of the system of Maxwell and kinetic equations in the case of a slowly changing total magnetic field over a distance of the order of the electron Larmor radius. It is shown that by varying H(o) one can study separately the dynamic nonlinear effect associated with the H(j) influence on the ballistics of conduction electrons, and the deviation from Ohm's law due to charge carrier heating by electric current.
