Abstract
A phenomenology describing recent transport measurements in high quality BiSrCaCuO films and crystals in which the angle θ of the applied field relative to the c-axis is varied is illustrated with fits to experimental results. The data show no evidence for conventional flux-flow; the model features phase-slip in a network of Josephson junctions. At low temperatures, low current densities, and for large fields, the resistivity varies approximately as ϱ ps (H,T,θ)= ϱ n [ I 0 (γ 1 3 (H,T,θ) 2)] 2 with γ≈ A T T c (T|Hcos(θ)|) . The 1 3 power is characteristic of a “stretched exponential” response.
