Claim 0:
1. A single magnetic heterojunction structure with both in-plane exchange bias effect and out-of-plane exchange bias effect comprising a substrate, an in-plane anti-ferromagnetic layer, an in-plane ferromagnetic layer, a nonmagnetic layer, a perpendicular ferromagnetic layer, and a perpendicular anti-ferromagnetic layer respectively from the bottom up; the in-plane ferromagnetic layer and the perpendicular ferromagnetic layer are coupled together through the nonmagnetic layer in the middle; the in-plane exchange bias effect occurs between the in-plane ferromagnetic layer and the in-plane anti-ferromagnetic layer as a result of the interfacial exchange coupling between the in-plane ferromagnetic layer and the in-plane anti-ferromagnetic layer, and the out-of-plane exchange bias effect occurs between the perpendicular ferromagnetic layer and the perpendicular anti-ferromagnetic layer as a result of the interfacial exchange coupling between the perpendicular ferromagnetic layer and the perpendicular anti-ferromagnetic layer.
