We have investigated electric field vs. current density(E-J) characteristics of Gd1Ba2Cu3O7-δ coated conductor over a wide range of E by deriving from magnetization relaxation and transport four-probe measurements. We succeeded in obtaining E-J characteristics between10-2 to 5×10-11 V/m, and analyzed the results within a frame work of the percolation transition model taking into account flux creep with a distribution of activation energy. This allows us to describe E-J characteristics as well as magnetic relaxation analytically based on the transport measurements. Clear deviation from the n-value model has also been confirmed from the experimental results.
