(a) The temporal evolution of ⟨ 𝑚 𝑥 ⟩ in the zoom of 59.55 ∼ 59.62 ns under 𝐽 = 1 . 6 0 × 1 0 7 A / c m 2 and 𝐻 𝑦 = 0 . 0 4 𝑀 𝑠 . (b) The magnetization precessional trajectory. (c) Micromagnetic simulation result of the snapshots of magnetization distribution. The colors represent the magnitude of the magnetization component ⟨ 𝑚 𝑧 ⟩ (pink positive, cyan negative).
