Abstract
The work justifies the selection of a sulfosalicylate copper–nickel electrolyte and its composition for obtaining nanostructures comprising alternate magnetic and nonmagnetic layers by a single-bath method. According to calculations of an equilibrium composition of the electrolyte and electrodiffusion fluxes of discharging species, in a neutral region of pH copper exists in the form of multicharged anions CuSSA3–, and the migration effects must reduce the rate of the mass transfer of copper-containing species with increasing current of the parallel reaction of discharge of nickel ions. Dependences of the partial current density of copper deposition on the electrode potential are studied at various values of pH of the copper and copper–nickel electrolytes. Experimental results are analyzed on the basis of modeling concepts. It is shown that the drop of the partial current density of copper deposition below its limiting value at potentials of deposition of a magnetic layer is connected with the emergence of migration effects.
