Perpendicular Giant Magnetoresistance and Magnetic Properties of Co/Cu Nanowire Arrays Affected by Period Number and Copper Layer Thickness

Figure 6

Magnetic hysteresis loops of Co/Cu nanowires with Co (50 nm)/Cu (5 nm) of different period numbers and the evolution of the coercivity () and remanence ratio (Mr/Ms) with the change of period number under the applied magnetic field parallel to the nanowires.
