Giant Magnetoresistance in Electrodeposited Films: Current Status and the Influence of Parameters

Electrodeposition of some alloys and multilayer which exhibits the giant magneto resistance (GMR) effect, have been the subject of numerous studies. They have great potential for technological applications, such as magneto resistive sensors and magnetic recording devices. GMR effect is more usually seen in multilayer and alloys structure, when two magnetic layers are closely separated by a thin non-magnetic spacer layer. This paper deals with the review of literature available on electrodeposition of alloys and multilayer for GMR application. The effect of thickness of magnetic, non-magnetic layers, number of bi-layers, electrolyte pH, electrolyte temperature, additives and annealing process on GMR properties will be discussed.
