The effect of ferromagnetic and non-ferromagnetic layer thicknesses on the electrodeposited CoFe/Cu multilayers

Simple electrodepositing of CoFe/Cu multilayers: Effect of ferromagnetic layer thicknesses

“…In that study (in Ref. [21]), the constant 4.0 nm Cu layer thickness separates the magnetic layers. However, in the present work, it is the first time that much thinner (0.5 nm) Cu layer was used to obtain the GMR effect on the electrodeposited CoFe/Cu multilayers as a function of magnetic layer thickness from 3 to 10 nm.…”

“…Therefore, the coupling between adjacent layers has to be lower to obtain GMR in the lower magnetic field such as multilayers and spin valves. For the CoFe/Cu multilayers produced by the electrodeposition, there are some reports on the dependence of their GMR and its sensitivity on ferromagnetic or non-magnetic layers thicknesses [8,[14][15][16][17][18][19][20][21]. Non-magnetic layer dependence of deposition potential were studied by Toth et al [8].…”

“…Sahin et al [20] presented the study of CoFe/Cu multilayer as a function of Cu layer thickness with electrodeposition technique. And our previous study [21] was about the electrodeposited CoFe/Cu multilayers and their systematically investigation of the magnetic and magnetoresistance effects as a function of thicknesses of ferromagnetic and non-magnetic layers. In that study (in Ref.…”

“…In the thin layers category, one of the most interesting for the research and applications of metal layers are thin magnetic layers, which can be used to obtain multilayer systems. These layers, for example, show the effect of giant magnetoresistance (GMR) [2,3]. Currently available modern techniques allow to largely form and shape the properties of layers with nanometric dimensions to specific needs [4,5], but often their disadvantage remains high cost and complicated manufacturing processes.…”

Structure and Giant Magnetoresistance of Co-Fe/Cu Multilayer Films Electrodeposited from Various Bath Formulations

“…[1][2][3][4][5][6][7] Since Co-Fe/Cu multilayers can be produced also by electrodeposition, there have been a lot of efforts in studying the GMR of electrodeposited Co-Fe/Cu multilayers. [8][9][10][11][12][13][14][15][16][17] However, relatively little amount of information is available about the optimization of the electrochemical parameters and the properties of the multilayers prepared under optimized conditions.…”
