Abstract
We report a comparative study of the giant magnetoresistance (GMR) in CPP (current perpendicular to the planes) geometry in two different types of multilayered nanowire systems: Co/Cu and Ni80Fe20/Cu. The nanowires were produced in the cylindrical pores of a polymer membrane using a pulsed electrodeposition technique. A GMR ratio as large as 78% was obtained for Ni80Fe20/Cu multilayered nanowires. Using the results of the Valet-Fert model for perpendicular transport we deduce the bulk and interface spin asymmetry coefficients and comparison is made between the two systems.
