Schematic DW motion and domain shapes at a current density J. The left upper panel shows the domain with U-D-U-D sketches and the magnetization orientation (thin black arrow) in domain and DWs. Once a current applied, the generated HSHE acting on the DWs are shown as red thick arrows, while the Oersted fields (HOersted) at both sides of the racetrack are shown as dash blue arrows. The left lower panel shows the corresponding change of the domain shape (denoted as dash thick black blocks) under the action of HSHE and HOersted. The right panel shows the effect of in-plane magnetic fields on the domain shape for Pt/Co/Ta
