Abstract

With a properly fabricated low-noise SQUID, we have studied the effects of microwave radiation on the noise behavior. Under an ac bias, with increasing microwave power, the critical current and the voltage modulation depth ΔV = Φ₀V_Φ/π decrease, but the SQUID resistance R_s increases, suggesting a dynamical interaction between the charge carriers and the electromagnetic wave. Furthermore, the microwave radiation modifies drastically the functional dependence of S_Φ and ΔV on ac bias current.
