Transport E-J characteristics in YBCO thin films have been studied as a function of temperature, T, magnetic field, B, and its angle, θ, under high magnetic fields up to 23 T. We carried out detailed measurements for the extended E-J characteristics at various T, B and θ. Analyzing the data within the framework of the percolation model, we extracted the factors related to the statistical distribution of critical current density, Jc. It is shown that if we assume that the scaling property and the angular dependencies of transition field, BGL, hold down to 55 K, BGL is estimated to be as high as 96 T in parallel field. The wide range measurements allow us to reveal the high potential of this material especially in high magnetic field region.
