Description
Critical currents of YBa2Cu3O7-δ bulk-sintered samples were measured at and above 77 K in the presence of magnetic fields. In moderate magnetic fields a H-n dependence with n<1 was observed. Transport measurements give n congruent 0.5, indicating that critical currents are limited by flux creep rather than by field quenching of Josephson junctions
