Abstract
The present invention relates to a kind of magnetic heterojunction structure and the method of controlling and achieving spin logic and multiple-state storage functions. The said single magnetic heterojunction structure comprises the substrate, in-plane anti-ferromagnetic layer, in-plane ferromagnetic layer, nonmagnetic layer, vertical ferromagnetic layer, and vertical anti-ferromagnetic layer respectively from the bottom up; the said in-plane ferromagnetic layer and the said vertical ferromagnetic layer are coupled together through the said nonmagnetic layer in the middle; in-plane exchange biases, namely exchange biases in the plane, exist between the said in-plane ferromagnetic layer and the said in-plane anti-ferromagnetic layer, and out-of-plane exchange biases, namely exchange biases out of the plane, exist between the said vertical ferromagnetic layer and the said vertical anti-ferromagnetic layer.
