Abstract: In high-Tc superconducting YBa2Cu3O7 δ films and at no applied magnetic field we found both positive and negative in-plane nonlocal resistance in the vicinity of a vortex-antivortex unbinding transition, as it was predicted recently. The sign of the nonlocal resistance depends on the probed region in the current-temperature diagram. Our results indicate that a negative nonlocal resistance is due to the motion of unbounded vortex-antivortex (V-A), whereas a positive sign is attributed to the motion of a 2D V-A ordered lattice.
