We present a theoretical analysis of the resonant macroscopic quantum tunneling in SQUID systems including the effect of both the temperature and the sweeping rate of the external flux, and the study of the phenomenon both in quasi-stationary and non-stationary conditions. We have found a very good agreement in the comparison of our results with the experimental data.
