From: Impact of layer count and thickness on spin wave modes in multilayer synthetic antiferromagnets
Spin wave profiles of the surface modes for the case \(N_L=30\). (a–c) corresponds to the surface mode highlighted by blue in Fig. 4, while (d–f) corresponds to the green one. The dynamic magnetization components are evaluated at \(k=-30\) rad/\(\mu\)m, while the thickness of the ferromagnetic layers are \(d_L=5\) nm, \(d_L=15\) nm and \(d_L=25\) nm. For better visibility, the SW profiles for ferromagnetic layers 1, 5, 10, 15, 20, 25 and 30 are illustrated. The time goes from zero (\(t=0\)) to the period as the color goes from yellow to red, respectively.
