Spin-transport at 4 K and 200 K. a, Platinum wires along x: Spin-signal Rel for a magnetic field applied along x (i.e the easy-axis) at 200K (blue dots) and 4K (blue circle). Spin-Seebeck signal Rth for a magnetic field applied along y at 200 K (black dots) and 4 K (black circle). (The distance between wires is about 200 nm, and the wire lengths 80 μm and the applied current 300 μA). b, Platinum wires along y: Spin-signal Rel for a magnetic field applied along x (i.e the easy-axis) at 200K (blue dots) and 4K (blue circle). Spin-Seebeck signal Rth for a magnetic field applied along x at 200K (black dots) and 4K (black circle). (The distance between wires is about 500 nm, and the wire lengths 160 μm for these second generation of devices and the applied current 600 μA)
