摘要：
The fabrication and physical properties of DC SQUIDs using Bi(Pb)SrCaCuO thin films are reported. The total Josephson critical current of DC SQUIDs with different microbridge widths (0.5-12μm) ranges from 8 μA to 5 mA. The observed quantum interference pattern under an applied magnetic filed is largely deformed and a discussion based on the multiple interference effect is given. The measured voltage modulation depth is found to be smaller than the calculated value. The Josephson critical current exhibits a (1-T/Trmc)n dependence on temperature where n=1-2.5. © 1990.
