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

Figure 5

(a)–(e) The CPP-GMR curves of Co (50 nm)/Cu (3 nm), Co (50 nm)/Cu (5 nm), Co (50 nm)/Cu (10 nm), Co (50 nm)/Cu (18 nm), and Co (50 nm)/Cu (30 nm) multilayered nanowire arrays under applied magnetic field parallel to the nanowires. (f) The relationship between the CPP-GMR ratio and different thicknesses of the Cu layer of the Co/Cu multilayered nanowire arrays under magnetic field parallel to the nanowires.
