Abstract
The nature of the resistive transition for a current applied parallel to the magnetic field in high-Tc materials is investigated by numerical simulation on the three-dimensional Josephson junction array model. Using finite-size scaling it is shown that for samples with disorder the temperature Tp of the c-axis resistivity transition corresponds to a percolation phase transition of vortex lines perpendicularly to the applied field. The value of Tp is higher than the temperature of the resistive transition for j⊥H, but decreases with the thickness of the sample and with anisotropy. We predict that critical behavior around Tp should reflect in experimentally accessible quantities, as the I-V curves. © 1996 The American Physical Society.
