Current-induced synchronized magnetization reversal of two-body Stoner particles with dipolar interaction Project supported by the National Natural Science Foundation of China (Grant No. 11274236) and the Deutsche Forschungsgemeinschaft via SFB 689. |
(color online) (a) Phase diagram in the PERP configuration of the magnetization self-precession in parameter η–aI plane, where the color is proportional to the self-oscillation amplitude and the two dashed lines show the analytical solutions of the critical switching current. (b) Self-oscillation curve of mz (t) at η = 0.31 and aI = 0.06. Inset shows the spatial trajectories of the magnetization vector and its projections. Other parameters are the same as those in Fig. |
