A dynamic system has been constructed that describes the dynamics of magnetization in a magnetic random-access memory element based on the spin Hall effect. The configuration of a cell with perpendicular anisotropy of the active layer and the dynamics of magnetization in the layer under the influence of charge-current pulses and an external magnetic field are considered. A qualitative analysis of the dynamic system was carried out. The equilibrium states of the system are identified and a classification of the main dynamic modes is carried out. The critical value of the switching current is calculated. Keywords: spintronics, orbitronics, magnetization, Landau-Lifshitz-Hilbert equation, spin Hall effect, spin current, charge current, spin torque.
