Abstract:
Magnetic wires that include cobalt, nickel, and platinum layers show improved domain wall motion properties, when the domain walls are driven by pulses of electrical current. These wires 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 platinum and cobalt layers are arranged.
