Abstract
Micro-bridges are fabricated with YBa2Cu3O7-8 thin films prepared by CVD method. The thickness of the bridge is ranging from 0.2 to 1 µm and the width and length are both about 1 µm. The critical current density of the bridge is ranging from 104 to 105 A/cm2 at 77K in zero field. The bridge shows clear ac and dc Josephson effects. However, temperature dependences of critical current show Ic oc (1-T/Tc)3/2, which suggests the transport current is superconducting bulk current and not Josephson current. The single bridge looks like a typical Josephson junction and all transport current in the bridge behaves as Josephson current.
