The deposition potentials were selected - 1.5 V for magnetic layers and - 0.3 V for non-magnetic layers with respect to saturated calomel electrode. The current-time transients were obtained during the deposition process. The X-ray diffraction was used to define the structure of the multilayers. The multilayers were found to be face-centred cubic structure such as bulk Cu. Their lattice parameter and inter-planar distances values confirm this result. The magnetic measurements were performed at room temperature under 2 kOe external magnetic field. The results show that the saturation magnetization gradually increased from 27 to 50 emu/cm(3) with increasing 0.025 to 0.05 M Fe concentration in electrolyte, and in the multilayer prepared from the electrolyte containing 0.1 M Fe concentration, this value drastically decreased to 18 emu/cm(3). The magnetoresistance measurements were carried out in magnetic fields in the range of +/- 1.2 kOe. The high GMR value (18 %) and sensitivity (4.4 %/Oe) were obtained for this multilayer.eninfo:eu-repo/semantics/closedAccessPhysicsElectrodepositionGiant magnetoresistanceGMR sensitivityCoFe/Cu multilayerElectrodeposited Co/Cu multilayersLayer thicknessesSuperlatticesFilmsCoElectrochemical depositionElectrodepositionElectrodesElectrolytesMagnetic materialsMultilayersReductionSaturation magnetizationX ray diffractionCoFe/Cu multilayersCurrent-time transientDeposition potentialDeposition processExternal magnetic fieldGMR sensitivityMagnetoresistance measurementsSaturated calomel electrodeGiant magnetoresistanceArticle0004355770000322-s2.0-8503765236721952200317https://doi.org/10.1007/s10948-017-4497-3Physics, appliedPhysics, condensed matterCopper; Coercivity; Saturation Magnetization1557-1947
