The tunneling current is obstructed when the two ferromagnetic layers have opposite orientations and is allowed when their orientations are the same.
若两侧的铁磁层磁性方向相反，穿隧电流就被挡住，反之则可通过。
Applying the opposite voltage bias to widen the tunneling gap and raise the electrical resistance would reopen the switch.
施加反向电压以增大穿隧间隙，提高电阻，可以重新将开关断开。
