Micromagnetic Simulation of Coupled Magnetic Oscillators Driven by Spin-Transfer Torque

In this work, an attempt is made to analyze the behavior of coupled magnetic oscillators driven by spin-transfer torque using a numerical method based on the Landau–Lifshitz equation. A simplified geometric model is used to reduce the computation time. The model is evaluated by comparison with recently reported experiments in terms of the synchronization dependence on the injection current and the distance between the two magnetic oscillators.
