摘要：
Step edge junction dc SQUID has been made from single layer YBa2Cu3O(x) thin film. Step edge was formed on SrTiO3 substrate by low energy Ar+ milling. C-axis oriented YBa2Cu3O(x) thin film was deposited by off-axis rf sputtering and patterned across the step edge by photolithography and Ar+ milling to form the SQUID loop. The SQUID showed periodic modulation signal responding to external magnetic field at 77 K and has the characteristics of 2I(c) congruent-to 40 muA and R(n) congruent-to 0.24 OMEGA.
