Description
We present evidence for forced topological entanglement of line-like vortices in the liquid regime of YBa2Cu 3O7-δ with columnar defects. By splaying the defects within a fixed plane (in-fan) we create a c- axis phase coherent vortex (string) structure which correlates with anisotropic dissipation. The high-field vortex motion is open-quotes easyclose quotes in fan and open-quotes hardclose quotes across fan in crystals emdash a signature of forced entanglement by a small angle splay. The high-field anisotropy is surprisingly reversed in thin films, where forced entanglement is absent. copyright 1997 The American Physical Society
