J induces a torque Ï„J along the +q-direction. The DW (white circle) initially sits in the FM-region immediate next to the FM-SAF boundary. Two cases \(H_{fl}^ +\) (left panel) and \(H_{fl}^ -\) (right panel) that correspond to positive and negative Hfl along the easy z-axis, respectively, are considered.
