“…Similar st patterns were observed and discussed also in Refs. [2,17]. Here we go a step forward, and clarify how the magnetic response depends on the choice of ( , ) combinations by analyzing different regions of the density plot in Fig.…”

“…In the past few years many efforts have been devoted to the theoretical study of the magnetic response of ferromagnetic anomalous Josephson junctions (JJs) [44,33,40,42,3,43,41,32,2,34,17,37,30], thus offering a path of concrete applications based on the electrical control of the magnetization in a so-called 0 -junction. A realization of such junction consists essentially of a superconductor-ferromagnetsuperconductor (SFS) Josephson junction with an intrinsic spin-orbit coupling (SOC).…”

“…The authors established the intervals of the parameters where the magnetization reversal is realized. The periodicity in the occurrence of intervals of the reversal of the magnetic moment with a change in the parameter of the spin-orbit coupling, the parameter of the Gilbert damping and the ratio of the Josephson energy to the magnetic energy were also found [5].…”

“…We see that this dependence reflects the periodicity in the occurrence of intervals of the reversal of the magnetic moment, found in ref. [5] (see also [13]). The width of the intervals stressed by dash lines, in which the switching takes place coincides fairly well for w = 0.01 and w = 1.…”

We have investigated the dynamics of magnetization under a current pulse in a φ0 - junction with a direct coupling between the magnetic moment and the superconducting current. The correspondence between the magnetization value at the end of the pulse mz * and the realization of the magnetization reversal along the easy axis of the ferromagnetic is considered. The crucial influence of the ratio w of the ferromagnetic frequency to the characteristic frequency of the Josephson junction on the results of reversal predictions is demonstrated. Effect of w magnitude on the manifestation of periodicity bands in the mz * dependence on the model parameters is shown. There is a critical value of the Gilbert damping, above which the magnetization reversal is not realized. It is shown that at small w the magnitude mz * can be as a criterion of magnetization reversal. I.e., if mz * <0, the magnetization reversal would happen with 100 percent probability. The results can be used in various areas of superconducting spintronics, in particular, to create a memory element based on the Josephson $ {\varphi_0} $ junction

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.
