摘要: By means of a novel technique rotating the applied current we have directly measured influence twin boundaries on vortex motion in ${\mathrm{YBa}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7}$ single crystal. The results indicate that effect planes dynamics starts to develop below certain temperature, being responsible for an anisotropic viscosity liquid state and guided solid state.
