The output voltage of a dc superconducting quantum interference device (SQUID) containing a resistive sectionRsoscillates at a frequency &ngr;q=Vs/ &fgr;0(&fgr;0=flux quantum) when a current controlled voltageVsis maintained acrossRs. These oscillations have been observed from ∼10−1to 1011Hz, usingRsvalues ranging from ∼10−10to ∼10−3&OHgr; in low inductance (∼10−10H) point contact SQUID loops. At high frequencies, they manifest themselves in the dc current‐voltage characteristics by inducing extra current steps.
