AbstractPersistent currents and magnetic susceptibility of two-junction quantum interferometers are calculated by means of perturbation analysis by solving, to second order in the SQUID parameter β, the coupled non-linear differential equations governing the dynamics of this superconducting device in the absence of bias current. Comparison is made with results obtained to first order in β
