Claim 6:
7. The method of adjusting and controlling the exchange biases in the two directions to achieve spin logic functions according to claim 6, wherein in the step ii), a process of achieving a AND logic function is as the followings:
current pulses and an external field (external field Hx=+100 Oe; current pulses Ix=+19 mA) are applied at the same time in the first and second channels to set the directions of in-plane exchange biases in the first and second channels and the magnetization directions of the in-plane ferromagnetic layers to the +x direction; then, the RH-Ix loops in the first and second channels flip anticlockwise; when the applied current pulses Ix=+18 mA, the magnetic moment of the perpendicular ferromagnetic layer in every single channel is upward; conversely, it is downward when the applied current pulses Ix=−18 mA. When I1=I2=+18 mA, namely when both logical inputs are “1” (where: I1 and I2 represent the current pulses applied in the first and second channels respectively), the magnetization directions of the perpendicular ferromagnetic layers in the first and second channels are both upward, and the corresponding logical output is “1”, thus achieving the AND logic function.
