Micro-magnetic simulation of switching. (a) Micro-magnetic simulated magnetization switching in Device 1. The transition is obtained with a simulated spin-current pulse of amplitude 3 × 106 A/cm2 and duration 13 ns in the horizontal arm. (b) The Switching between two remanent states are also performed in Device 2 with a simulated spin-current pulse of amplitude 7 × 106 A/cm2 and duration 13 ns in the blue arm (2–5 arm). The arrows indicate the magnetization direction. The color map is shown in Fig. S1 of supplementary materials.
