Abstract :
A variety of techniques to reproducibly engineer microbridges in high-quality epitaxial YBCO films exist. A report is presented on two such techniques that have resulted in high-yield processes for fabricating both DC and RF SQUIDs operating at temperatures as high as 82 K. The results of these devices (step-edge microbridges) and focused-ion-beam microbridges) are compared with those of several other structures under investigation by other researchers
