Electrochemical deposition and characterization of CoNi alloy thin films

Cobalt and Nickel based alloys in industries attracted many researchers due to its significant features of film thickness, structural, surface morphology with film composition and magnetic properties. The present work focused the film thickness, structural, compositional and magnetic properties of Cobalt Nickel alloy thin film growth by simple, low cost, economically friendly chemical method. The films deposited on Copper substrate by galvanostatic electrodeposition technique. Structural properties showed that the deposited films have polycrystalline in nature. Structural features showed that the deposited films have polycrystalline nature with cubic structure. The crystallites are found to exhibit most prominent reflection along (2 0 0) plane. The parameters such as crystallite size, strain and dislocation density are determined. The films deposited are found to be smooth surface with stoichiometry. Vibrating sample magnetometric measurements have been used to determine the magnetic properties of the deposited films. The parameters such as coercivity, remanence, retentivity of the deposited films are estimated. (c) 2021 Elsevier Ltd. All rights reserved.
