Abstract

Zn-Fe-Ni films were fabricated on aluminum substrate under potentiostatic deposition condition and their composition, magnetic property and structure were evaluated as a function of FeSO4 concentration in electrolyte. The bath was consisted of 40 g/l ZnCl2, 10 g/l NiCl2.6H2O, (5 to 30) g/l FeSO4.7H2O, 25 g/l C6H5Na3O7.2H2O, 16 g/l H3BO3, 25 g/l NH4Cl, 1 g/l gelatine. Cyclic voltammetry of Zn-Fe-Ni alloy was performed in to study electroplating process of the films. The structural and morphological properties of the as-deposited films were studied using X-ray diffractometer and scanning electron microscope. The films form with a high zinc content and show hexagonal close packed (HCP) structure with a strong (101) orientation. Magnetic properties were measured using a vibrating sample magnetometer. It is found that the composition, structure and magnetic properties of the thin films exhibit strong dependence on the composition of the bath electrolyte.
