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

Figure 4

(a) Magnetic hysteresis loops of the Co/Cu nanowires with Co (50 nm) and Cu varied from 3 nm to 30 nm. (b) Evolution of the coercivity () and remanence ratio (Mr/Ms) with the change of Cu layer thickness under applied magnetic field parallel to the nanowires.
