Magnetic Properties of Thin Cu/Co Multilayers Made by Electrodeposition
Journal of Magnetics, Volume 10, Number 3, 30 Sep 2005, Pages 118-121
Abstract
We have investigated the magnetic properties of electroplated thin Cu/Co multilayers by using electrolytes made of copper sulphate and cobalt sulphate and by applying alternating plating voltage. While the multilayers plated with pure electrolyte showed superparamagnetism, those plated with organic additives showed ferromagnetic behavior. These changes are attributed to the so-called 'self-annealing' effect and reduction of grain size caused by the organic additives.
