摘要：
Magnetic wires that include two antiferromagnetically coupled magnetic regions show improved domain wall motion properties, when the domain walls are driven by pulses of electrical current. The magnetic regions preferably include Co, Ni, and Pt and exhibit perpendicular magnetic anisotropy, thereby supporting the propagation of narrow domain walls. The direction of motion of the domain walls can be influenced by the order in which the wire's layers are arranged.
