摘要：
A dc superconducting quantum interference device (SQUID) is fabricated on an amorphous Y-Ba-Cu-O film by a photolithographic technique and successive post-annealing treatment. The SQUID shows periodic and symmetric behavior in the voltage versus magnetic-flux curves (V-PHI curves). No multiple periodicities are observed. The transfer function partial-V/partial-PHI for output voltage is about 90 20-mu-V/PHI-0 at 4.2 and 56 K, respectively. It is expected that the SQUID contains only two symmetric active Josephson junctions.
