(a) SEM image of a CoFe-based lateral spin valve, with the electrical setup for GMR measurements. The inter-electrode gap is 150 nm wide from centre to centre (i.e. 100 wide from edge to edge). The non-magnetic channel is made of Cu. All nanowires are 50 nm wide. CoFe wires are 15 nm thick, while Cu wires are 80 nm thick. (b) Corresponding GMR measurement at 10 K, obtained with a magnetic field parallel to the ferromagnetic electrodes. The relative resistance variation is ΔR/R = 10.5%.
