    In this report, the temperature dependent characteristics are investigated for the step-edge YBCO SQUID. The experimental results show a linear relationship between Ic and T. This reveals a SIS-like tunneling behavior for the step-edge YBCO SQUID. The peak-to-peak voltage Vpp in the V-Φ curve of the SQUID was found to decrease almost linearly when the temperature was raised from 10 K to 60 K. As the temperature approached to the Tc of the SQUID, the Vpp was reduced abruptly and deviated from the theoretically predicted curve. This deviation may be due to the variation of the inductance of the SQUID at various temperatures.
