Description
The measurements of the intergrain (Josephson) critical current and its dissipation were performed in granular superconductors of YBCO. YBCO/Ag (2 wt.%), and YBCO/Ag (4 wt.%). A self-sustaining supercurrent flowing in a superconducting ring and a contactless detection of its magnitude with a Hall probe were used in these studies. The results suggest that a small variation in the integrain coupling energy is responsible for a weak Josephson flux pinning and a decay of the critical current. 3 refs., 2 figs
