摘      要：We study the response of a superconducting quantum interference device （SQUID） to an alternating magnetic field. It is found that, for some suitably selected parameters＇ values, we can obtain stochastic resonance for the amplitude of the steady average voltage of the SQUID versus the dichotomous noise strength, and frequency （stochastic） resonance for the amplitude of the stationary average voltage of the SQUID as a function of the frequency of the alternating magnetic field. Our results can be useful for electrical power generation using the alternating magnetic field energy of a SQUID.
