We analyze the voltage-current characteristics of high quality c-axis oriented YBa2Cu3O7-δfilms with Tc0≈91 K. The films were dc sputtered in a pure oxygen atmosphere on SrTiO3(100) substrates and then patterned in a shape of a long strip. The voltage-current characteristics are modeled with single or multiple Gaussian distributions of depinning currents. We derive the distribution features as a function of the applied magnetic field at different temperatures.
