Abstract

We have measured I-V characteristics of our three different width YBCO grain-boundary short Josephson Junctions for device applications. All the junctions showed clear linear RSJ-like I-V characteristics at temperatures above 5 K. High values of the critical current times normal resistance, I_cR_n, products were observed in our junctions. The high I_cR_n values found in these junctions could be of interest for the fabrication of high-sensitive Josephson-junction based radiation detectors. Moreover, a new anomaly of normal resistance (R_n) temperature dependence is observed and presented in this work.
