a Schematic of device structure and measurement configuration. b Two-probe current-voltage curves of Co/In-contacted channel (upper panel) and Co-contacted channel (lower panel) measured between the injection and detection electrodes under different temperatures. Indium thickness in this device is 4 nm. c Nonlocal spin valve signal of Co/In-contacted channel measured at room temperature. d Hanle spin precession data for Co/In-contacted channel measured at parallel and anti-parallel states. The red solid lines are fitted curves.
