a A schematic of the device and measurement geometry to measure the non-local spin signal with a ferromagnetic detector in graphene across the graphene-MoTe2 heterostructure. b, c Spin valve and Hanle spin precession measurements, respectively. d A schematic of the device and measurement geometry to measure the non-local spin-galvanic signal (VSGE) with non-ferromagnetic detectors (Ti/Au) along the Hall-cross of graphene-MoTe2 heterostructure. e The spin-galvanic signal, VSGE, is measured with varying in-plane magnetic field (Bx) at room temperature. f The spin-galvanic signal was detected via Hanle spin precession with varying out-of-plane magnetic field (Bz) along with Hanle fitting.
