Claim 5:
6. A method of adjusting and controlling the exchange biases in the two directions to achieve spin logic functions in the single magnetic heterojunction structure according to claim 1 comprising the following steps:
i) a Hall bar device with two current channels but only one voltage channel is designed, the two current channels are a first channel and a second channel;
ii) current pulses and an external field are applied at the same time to set the direction of in-plane exchange bias in the first channel; then, the same procedures are followed to set the in-plane exchange bias in the second channel;
the alignment of magnetic moments in the first and second channels are controlled by controlling the directions of in-plane exchange biases and the directions and size of the input current pulses in the first and second channels, which is as follows: first, the in-plane exchange bias in the first and second channels are set to different configurations during the logical operation; then, under zero field, different current pulses are input into the first and second channels as the logical inputs, and the Hall voltage or Hall resistance of the whole device is taken as the logical output to achieve the spin logic functions.
