Abstract
Critical currents of an Y1Ba2Cu3O7–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 Jc 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.Keywords
