Abstract

The critical current densities of chemical vapor deposition (CVD) processed YBa2Cu307-<5 films were resistively measured in fields up to 13 T and in a temperature range from 4.2 to 77.3 K. For B perpendicular to the c-axis (2?_L c), an anomaly in the temperature dependence of Jc was observed at Td = 50-60 K and the field dependence of Jc drastically changed at Td. Since Td was almost in agreement with the estimated dimensional crossover temperature Tco, it is sug gested that the change of dimensionality influences the Jc properties.
