Abstract

The critical current density Jc(B,T) is measured to 15 T for c-axis-perpendicular expitaxial thin films of YBa2Cu3O7 with Jc(0,77 K) of order 106 A/cm2. Even in the least-favorable perpendicular orientation, critical currents can exceed 5×105 A/cm2 at 20 K in 15-T fields. Thermally activated flux motion (flux creep) is prominently observed, and can in large part explain the magnitude, temperature, and field dependence of the high-field critical currents.
