Claim 8:
9. The method of adjusting and controlling the exchange biases in the two directions to achieve spin logic functions according to claim 6, wherein in step ii) a process of achieving a NIMP logic function is as followings:
current pulses and an external field (external field Hx=+100 Oe; current pulses I1=+19 mA) are applied in the first channel to set the direction of in-plane exchange biases in the first channel and the magnetization direction of the in-plane ferromagnetic layer to the +x direction;
current pulses and an external field (external field Hx=−100 Oe; current pulses I2=+19 mA) are applied in the second channel to set the direction of in-plane exchange biases in the second channel and the magnetization direction of the in-plane ferromagnetic layer to the −x direction;
then, the RH-Ix loop in the first channel flips anticlockwise; when the applied current pulses I1=+18 mA, the magnetic moment of the perpendicular ferromagnetic layer in the first channel is upward; conversely, it is downward when the applied current pulses I1=−18 mA;
the RH-Ix loop in the second channel flips clockwise; when the applied current pulses I2=+18 mA, the magnetic moment of the perpendicular ferromagnetic layer in the second channel is downward; conversely, it is upward when the applied current pulses I2=−18 mA;
therefore, when the input of the first channel is “1”, namely I1=+18 mA, and the input of the second channel is “0”, namely I2=−18 mA, 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 NIMP logic function.
