Impressment of Cobalt and Nickel based alloys in industries for the last few years attracted many researchers due to its significant features of physical, chemical and magnetic properties. The present work focused the structural, compositional, morphological and magnetic properties of Cobalt Nickel alloy thin film growth by one of the chemical methods. Thin films of Cobalt Nickel have been deposited on various substrates by means of low cost galvanostatic electrodeposition technique. Structural investigation showed that the deposited films have face centred cubic structure with orientation of crystallites along (111) plane. The structural parameters such as crystallite size, rms microstrain, dislocation density and stacking fault probability are estimated for the deposited films. Morphological features along with film composition showed that the deposited films have smooth surface with stoichiometry. Magnetic properties such as coercivity, remanence, retentivity was estimated and the results are reported.
