Abstract
We study various physical phenomena in a $\varphi _{0}$ Josephson junction with a direct coupling between magnetic moment and Josephson current. We demonstrate three types of effects that lead to magnetization reversal in the ferromagnetic layer, including the magnetic moment reversal 1) by a pulse of superconducting current, 2) by a linearly decreasing bias voltage in the $\varphi _{0}$ -junction, and 3) by a pulse of external magnetic field in an rf-SQUID with a $\varphi _{0}$ -junction. The influence of the model parameters of the systems on magnetization reversal is investigated in detail. The observed features might find applications in different fields of superconducting spintronics.
