Essay

The influence of the point-like disorder and the ac current on the two-dimensional vortex dynamics in a superconductor in the mixed state and connected with it nonlinear anisotropic resistive response is stydied. Explicit current-angle- dependent expressions for anisotropic longitudinal and transverse nonlinear magnetoresistivities are represented and analyzed. The Langevin equation for a guided vortex motion in a tilted cosine pinning potential in the presence of an ac current is exactly solved.
