Sonoelectrochemical Synthesis of Metallic Multilayer Nanocomposite and their Characterization

Abstract

Multilayers have received increasing attention in recent years because of their unique properties. These materials comprised of alternating layers of different metals and/or alloy is expected unusual and enhanced electrical, optical, magnetic and mechanical properties when the sublayer thickness is confined to the nanometer scale. In this work we tried to Cu/Ni multilayer by varying the concentration of the bath with changing potential for alternate deposition of nano multilayer. Our conclusions are the result of combining experimental work with chraterization with XRD, SEM, AFM and and nanoindentation with special concentration of the different growth texture of the multilayers grains and growth mechanism with GMR studies. We argue that this approach is the best avenue to obtain accurate information about the texture and quality of metallic multilayers. The study of physical properties of multilayers (structural, elastic, magnetic, and transport) is one of the most prosperous and rich branches of materials science today.
