Electrodeposition is a promising candidate for the preparation of magnetic nanostructures. Multilayered fcc Co/Pt and CoNi/Pt nanostructures grown on a Pt (111) or Cu (111) single-crystal substrate by electrodeposition under potential control respectively exhibit remanent perpendicular magnetization and large coercivity, which depend on the deposition overpotential and hence the multilayer growth mechanism. Giant magnetoresistance and oscillatory interlayer coupling have been observed ire a fcc (111) textured Co/Cu multilayered nanostructure. Moreover, a large saturation magnetoresistance of more than 20% has been achieved at room temperature for a heterogeneous Co-Cu alloy, which consists of ultrafine fcc Co-rich clusters in a nonmagnetic Cu matrix.
