(color online) Example of snapshots for the relaxation process of free layer with perpendicular magnetic anisotropy (PMA) constant K_u = 0.2 × 10⁶ J/m³, initially anti-parallel (AP)-states. (a) Initial state: uniform out-of-plane. (b) The spins at the edge have a deviation from the +z-axis. (c) Initial uniform area shrinks gradually. (d) Vortex state formation.
