DYNAMICS OF D-WAVE VORTICES - ANGLE-DEPENDENT NONLINEAR HALL-EFFECT

We study the dynamics of vortices in d-wave superconductors using a ph enomenological time-dependent Ginzburg-Landau equation with mixing of s- and d-wave components. We present numerical simulations under an ex ternal driving current J oriented with an angle phi with respect to th e b crystal axis, calculating the vortex motion and induced electric f ields for kappa = infinity. We find an intrinsic Hall effect for phi n ot equal 0 which depends on similar to sin(4 phi), and increases nonli nearly with J.
