Caption: In the three-terminal device measurement geometry, a current is applied to contacts 1 and 2, and a voltage is measured across contacts 2 and 3. Electrical spin injection produces spin accumulation in the transport channel under the magnetic contact 2 and a corresponding output voltage. When a magnetic field Bz is applied, the injected spins precess and dephase, and the spin accumulation decreases to zero.
