Abstract:
It was found that the normal e-e collisions (hydrodynamic electron flow) increase the electrical resistance of a conductor with inhomogeneous magnetic properties. A new hydrodynamic transport effect has been found: existence of eigenmodes of coupled oscillations of the full current and non-equilibrium spin polarization in closed conductor. The frequency and decay time of these oscillations have been calculated. The electrical resistance R of a closed conductor has been also calculated. It has been shown that dependence of Re[1/R(ω)], where ω is the external electromotive force frequency, has a maximum, which corresponds to the eigenmodes of full current oscillations. It has been shown that the similar effects are possible for the electron system over a liquid helium surface when an inhomogeneous magnetic field is applied. (in Russian)
