Fig. 5: Ordinary free layer droplet and quasi-periodic droplet pair.

a–f Droplet snapshots together with g–j the time evolution of Mx (in-plane) and Mz (out-of-plane). The magnetization of the free layer (FL) and the reference layer (RL) are given by red and black lines, respectively. The blue circles in g–j show the corresponding time and magnetization of the snapshots.
