Popis:	The processes of magnetization reversal by the transport current self-field of a high-temperature superconductor sample with ferromagnetic particles as defects in the presence of an external magnetic field and current-voltage characteristics of the system have been calculated using the Monte Carlo method. It has been found that an S-shaped feature is observed in the current-voltage characteristics due to a change in the effective interaction of the magnetic moments of impurity particles with a vortex system of the superconductor, which is induced by the magnetization reversal of ferromagnetic impurities under the influence of the local magnetic field of the vortex lattice. It has been demonstrated that, in the vicinity of the instability, there is the motion of a wave of magnetization reversal of magnetic defects (magnetic domain) and waves of annihilation of Abrikosov vortices (vortex density domains).
