The phase dynamics of a SQUID consisting of two Phi-0 junctions has been investigated [1,2]. The current-phase relation of such junction has a phase shift proportional to the magnetic moment, perpendicular to the gradient of the asymmetric spin-orbital potential. The phase shift allows one to manipulate the internal magnetic moment using the Josephson current. The reverse phenomenon leads to the appearance of the DC component in the superconducting current [3-5]. Based on the numerical solution of the equations of the resistive model for Josephson junctions and the Landau - Lifshitz - Gilbert equations for the magnetic moment of ferromagnetic layer, the current-voltage characteristic and time dependences of the voltage and components of the magnetic moment are calculated. The double resonance in this system is observed, i.e., the simultaneous realization of ferromagnetic resonance and excitation of the SQUID eigenmode. The double resonance in the considered SQUID makes possible the detailed investigation of the resonance properties of Phi-0 junction.
