Abstract
By means of a novel technique of rotating the applied current we have direc tly measured the influence of twin boundaries on the vortex motion in a YBa 2Cu3O7 single crystal. The results indicate that the effect of twin planes on the vortex dynamics starts to develop below a certain temperature, being responsible for an anisotropic viscosity in the vortex liquid state and a guided motion in the solid state.
