Abstract

The output voltage of a dc superconducting quantum interference device (SQUID) containing a resistive section R_s oscillates at a frequency ν_q =V_s/ φ₀ (φ₀=flux quantum) when a current controlled voltage V_s is maintained across R_s. These oscillations have been observed from ∼10 ^-1 to 10¹¹ Hz, using R_s values ranging from ∼10^-10 to ∼10 ^-3 Ω in low inductance (∼10^- ¹⁰ H) point contact SQUID loops. At high frequencies, they manifest themselves in the dc current-voltage characteristics by inducing extra current steps.
