Abstract

Critical currents of an Y₁Ba₂Cu₃O _7-δ film prepared by a chemical vapor deposition technique have been measured resistively. Excellent critical current properties in high fields up to 27 T are obtained at 77.3 K. The value of J_c is 4.1×10⁵, 1.9×10⁵, and 6.5×10⁴ A/cm² at 2, 10, and 27 T, respectively. The upper critical field defined by zero resistivity is estimated to be 35 and 180 T at 77.3 and 0 K, respectively. A peak effect in the critical current is observed at high fields.
