Claim 9:
10. 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 Converse 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 clockwise; when the applied current pulses I1=+18 mA, the magnetic moment of the perpendicular ferromagnetic layer in the first channel is downward; conversely, it is upward when the applied current pulses I1=−18 mA;
the RH-Ix loop in the second channel flips anticlockwise; when the applied current pulses I2=+18 mA, the magnetic moment of the perpendicular ferromagnetic layer in the second channel is upward; conversely, it is downward when the applied current pulses I2=−18 mA;
therefore, when the input of the first channel is “0”, namely I1=−18 mA, and the input of the second channel is “1”, 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 Converse NIMP logic function.
