Abstract

We present the experimental results of (Co/CoxZn1-x)n (with x≤6.5%) films grown from electrochemical dual bath based on (CoSO4 7H2O) and (ZnSO4. 7H2O). X-ray diffraction patterns have shown the polycrystalline structure of CoZn layers with the structural lattice parameters close to those of the monoclinic CoZn13 compound. With the interfacial effects we have explained the magnetization behaviour for the (Co/CoxZn1-x)n multilayers. The atypical profile of the magnetic hysteresis curves indicates that our samples present two magnetic components with different anisotropy.
