We observed the shifted Hall loop in Gd-Fe wire with IrMn layer although it has perpendicular anisotropy. It means that the magnetization in Gd-Fe layer was pinned perpendicularly by the IrMn layer.We observed SOT-CIMS in Gd-Fe wires under various in-plane magnetic field (H_X). The SOT-CIMS was obtained in the Gd-Fe wire with IrMn layer with applying the out-of-plane magnetic field to cancel the exchange bias field. We found that the critical current density J_C in the Gd-Fe wire with IrMn layer was smaller than that without IrMn layer.
