Abstract
The motion of magnetic flux quanta (fluxons) in long Josephson junctions (LJJ) under action of direct and random currents is under investigation. The velocity distribution function of fuxons is calculated which, even in the absence of the direct current component, is non-Gaussian. As a consequence, the current-voltage characteristic of a noise junction differs from that for a regular one. The dependence of the voltage difference on the current for junctions, both with and without the noisy current component, is shown to be non-monotonic. There is a good agreement between the calculation data and the numerical simulation results.
