摘要：
The predominant d-wave pairing symmetry in high temperature superconductors allows for a variety of current-phase relations (CPR) in Josephson junctions. In this presentation we report on direct experimental observations of the effects of non-sinusoidal CPR in YBCO dc-SQUIDs made with submicron 0/45degrees bicrystal junctions. We also present the effect of such CPR on the extrama positions of the critical current versus magnetic field measurements. (C) 2004 Published by Elsevier B.V.
