Abstract: A complementary device including a gate electrode, a channel, a source electrode connected to the gate electrode and the channel, and a first drain electrode and a second drain electrode connected to the gate electrode and the channel is provided. The first/second drain electrode is formed so that, in accordance with a voltage applied to the gate electrode, electron spins injected into the source electrode are moved from the source electrode to the first/second drain electrode through the channel while rotating in a first/second direction. Directions of the electron spins that reach the first drain electrode and the second drain electrode are opposite to each other.
