10. -8 Torr. The wire with trilayered structure was obtained after the resist mask was removed. Because of the large Cu-layer thickness, the interlayer exchange coupling between the NiFe layers is negligible. The width of the wire is 0.5 μm, and the sample has four current-voltage terminals, where the voltage is probed over a distance of 2 mm.
