- Аннотация: The magnetic proprieties of a nanopillar with multiple magnetic layers are dependent on the intrinsic parameters of each layer but also on the coupling between the layers. In this study, we analyze numerically the field-voltage diagram of a magnetic tunnel junction based nanopillar consisting of three coupled macrospin layers perpendicularly magnetized. The dipolar coupling between various layers together with the mutual spin-transfer torque increases the number of the possible stable states. Consequently, the diagrams become more complex having several new boundaries. The systematic evolution of the shape of the diagrams and their various boundaries are discussed upon changing the material parameters and the strength of the couplings. The control parameters for each boundary are identified, pointing thus out the required optimal conditions for memory application (MRAM) and less limitation on the cell writing.
