The measured nonlocal (NL) spin-valve signal Rnl=Vnl/Idc for spin injection from FGT with parallel (P) and antiparallel (AP) alignment of FGT and Co electrodes (red and blue arrows) on CVD graphene channel with an applied bias current I across the FGT/Gr junction and NL voltage Vnl measured by the Co detector, as shown in the measurement geometry in the inset. The reference Au/Ti contacts on FGT and graphene are represented by the black dots. The bottom panel shows the data for FGT as the detector and Co as an injector (schematic in the inset). The red (blue) dashed arrows show the magnetic field sweep directions. The switching fields for FGT and Co electrodes in the spin-valve measurement are indicated. The measurements were performed in Dev 1 at room temperature.
