Peculiarities of magnetic moment switching in the φ0-junction
Original language description
We have investigated the dynamics of magnetization under a current pulse in a phi(0)-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 m(z)* 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. The effect of the w magnitude on the manifestation of periodicity bands in the m(z)* 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 m(z)* can be considered as a criterion of magnetization reversal. I. e. , if m(z)* < 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 phi(0)-junction.
