| Abstract |
| | The normal form of the dynamical system describing the motion of the magnetization in the active layer of the three-layered STT-MRAM element was derived with the field-like component of the torque taken into account. The qualitative analysis of the dynamical system was performed. On the “field–current” plane the regions where the behavior of the trajectories is topologically equivalent, were determined. The critical lines separated the regions were found analytically. The results were compared with those obtained for the case without the field-like component of the torque in the equa-tion of the motion. |
