We have developed Josephson junctions and superconducting quantum interference devices (SQUIDs) in a superconductor‐normal‐superconductor edge‐junction design. These devices are unusual in that we use YBa2Cu3O7−xfor both the superconducting and normal layers. The only difference between the layers is the temperature of the substrate during deposition, 695 °C for the superconductor and 670 °C for theNlayer. The lower deposition temperature results in material with a significantly reducedTcand a higher resistivity. The Josephson junctions produced in this fashion haveIcRnproducts typically greater than 100 &mgr;V at 77 K. The SQUIDs are not fully optimized but have produced modulation depths of approximately 10 &mgr;V at 76 K. These SQUID results are similar to the best results in the literature. ©1995 American Institute of Physics.
