Abstract
We fabricatedc-axis oriented meas on YBa2Cu3O7−δ thin films. Columnar structures with an area of 20×20 μm2 and a depth of 0.1 μm were formed on oxygen deficient films with a critical temperature (T c ) of 64 K or less. The devices showed hysteretic I–V curves without any branches. The dependence of the critical current density on the temperature nearT c is explained by the Ambegaokar-Baratoff relation.
