Abstract
The current-voltage characteristics of high-quality YBCO thin films de posited onto MgO have been measured in both zero and finite applied ma gnetic fields. The wide dynamic range of the measurements, the high ex perimental precision and the observation of extremely well defined pow er law behaviour below the phase transition temperature have enabled u s to demonstrate that vortex glass scaling does not occur, and that 2D vortex unbinding provides a better account of the results.
