Abstract

We have fabricated and measured high-quality [100] Y-Ba-Cu-O grain boundary junctions in both symmetric and asymmetric configurations. High values of the critical current times normal resistance I_cR_n products have been systematically observed. The high I_cR_n values found in these junctions may be of interest for the fabrication of high-sensitive superconducting quantum interference devices.
