Abstract

Electrochemical method has been applied for preparing Co/Cu multilayered thin films. The layers were electrodeposited after injecting Co and Cu containing solutions in a flow exchanged supporting electrolyte solution. In X-ray diffraction at low angle range a long period peak could be observed, and in the middle angle region a single broad peak showing an average lattice spacing of the film was observed. The electrical resistance showed the properties of Giant Magnetoresistance (GMR). The GMR ratio showed a variation against Cu layer thickness as expected for anti-ferromagnetically coupled films. The maximum GMR ratio obtained in this study was 6.2% at room temperature for the film of [Co 2.0 nm/Cu 1.0 nm]15. Though we need further studies for choosing suitable deposition conditions, the electrodeposition method is a promising method for producing multilayered thin films.
