CHARACTERIZATION OF ELECTRODEPOSITED MAGNETIC MULTILAYERS

Electrodeposition,Fill prove to be a promising candidate for the prepa ration of magnetic nanostructures, Multilayered Co/Pt nanostructures g rown on a Cu(lll) single-crystal substrate by electrodeposition under potential control exhibit a remanent perpendicular magnetization and a large coercivity, which depend on the deposition overpotential and he nce the multilayer growth mechanism. Giant magnetoresistance and oscil latory antiferromagnetic interlayer coupling have been observed in a f ace-centered cubic (fcc) (111) textured Co/Cu multilayered nanostructu re. Moreover, a large saturation magnetoresistance of more than 20% ha s been achieved at room temperature for a heterogeneous Co-Gu alloy, w hich consists of ultrafine fee Go-rich clusters in a nonmagnetic Cu ma trix.
