Abstract
In this report, the temperature dependent characteristics are investigated for the step-edge YBCO SQUID. The experimental results show a linear relati onship between I-c and T. This reveals a SIS-like tunneling behavior for th e step-edge YBCO SQUID. The peak-to-peak voltage V-pp in the V-Phi curve of the SQUID was found to decrease almost linearly when the temperature was r aised from 10 K to 60 K. As the temperature approached to the T-c of the SQ UID, the V-pp was reduced abruptly and deviated from the theoretically pred icted curve. This deviation may be due to the variation of the inductance o f the SQUID at various temperatures.
