Resumen:
By means of a novel technique of rotating the applied current we have directly measured the influenceof twin boundaries on the vortex motion in a YBa2Cu3O7 single crystal. The results indicate that theeffect of twin planes on the vortex dynamics starts to develop below a certain temperature, beingresponsible for an anisotropic viscosity in the vortex liquid state and a guided motion in the solid state.
