The φ0 junction demonstrates a rich variety of dynamical states determined by parameters of the Josephson junction and the intermediate ferromagnetic layer. Here we find several peculiarities in the maximal amplitude of magnetic moment m ^ y, taken at each value of the bias current, which we correlate to the features of the IV-characteristics of the φ0 junction. We show that a kink behavior in the bias current (voltage) dependence of m ^ y along the IV-characteristics is related to the changes in the dynamical behavior of the magnetization precession in the ferromagnetic layer. We also demonstrate a transformation of the magnetization specific trajectories along the IV-curve, magnetization composite structures, and hysteretic behavior in the bias current dependence of m ^ y. Due to the correlations between features of m ^ y and the IV-characteristics, the presented results open a way for the experimental testing of the peculiar magnetization dynamics which characterize the φ0 junction.
