Preparation and magnetic properties of electrodeposited [Co/Zn] multilayer films

► The [Co/Zn]50 have been deposited SSSSSfrom sulfate baths by a dual bath procedure in potentiostatic regime. ► The microstructure and magnetic properties have a strong dependence both on the nature of the first electrodeposited layer onto Cu substrate. ► We report here the observation of significant values of GMR in [Co/Zn]50 multilayers. ► The thickness of the Zn interlayer plays a dominant role on the magnitude of the MR effect. ► The GMR contribution of about 30% in the case of [Co (5 nm)/Zn (2.7 nm)]50 films.
