Figure 5: LLG dynamics of skyrmion collision.
The parameter sets for the results shown in (a–d) correspond to the cases shown in Fig. 4a–d, respectively. The panels with blue frames show the magnetic textures on layer 1. In the figures (a–d), the magnetic textures on layer 2 are shown with red (purple) frames for the cases (A1) and (A2) ((B1) and (B2)). To represent the magnetic texture, the color code (e) is used. The trajectory of the skyrmion on layer 1 is shown by the blue curves. In the figures (a–d), the red (purple) curves are the trajectories of the skyrmion on layer 2 for the cases (A1) and (A2) ((B1) and (B2)). In the left panel of (b) at t = 250000, the red (blue) symbol × on layer 1 (layer 2) represents the center-of-mass of the skyrmion on layer 2 (layer 1). In figures (c,d), the white symbols × and + indicate the initial position of the skyrmion on layer 2.
