Description

We consider a model of the superconducting quantum interference device (SQUID) with a single $\phi_0$ junction based on the Landau-Lifshitz-Gilbert equations for the magnetization of the ferromagnetic layer and resistively shunted junction model for phase difference of $\phi_0$ Josephson junction. Within this model, a phenomenon of magnetization reversal is studied in a wide range of parameters using the MPI-based parallel implementation of the numerical simulation procedure. It was revealed that the intervals of the magnetization reversal have a periodic structure which depends on the amplitude of the external magnetic field pulse and on the inductance of the SQUID. One expects that the results are of interest within applications in design and optimization of modern superconducting electronics and spintronics.
