โœฆ Synopsis

We fabricated planar YBCO Ag/YBCO a nominal thickness of 300 8 junctions having lateral dimensions of lmm x lmm and . The junctions were prepared in situ using the laser ablation technique and contact masks to define the geometry. The critical current of the junctions in a magnetic field and in a microwave radiation shows response characteristic of an SNS Josephson Junction. In addition, the junctions show a novel nonlinear effect which to the best of our knowledge was not observed with conventional superconductors.

The transport and magnetic properties of pure Y-Ba-Cu-O and Y-Ba-Cu-O/Ag composites prepared by the co-precipitation method have been studied. The normal state resistivity decreases with addition of silver. The magnetic properties reveal that addition of silver to the YBCO sample degrades the superc

The electric property of a YBCO/Ag/Pb junction was examined by a novel measurement echnique using a superconducting galvanome~er. The residual resistance below Ic was less ~han 10-14 ohm cm 2 . The current-vol~age chracteristic above Ic was measured wi~h a voltage sensi~ivity of 10 pV.
