This work concerns the Fe50Pt50/Fe2Pt98 magnetic multilayers electrodeposited from ionic liquid system. Iron concentration in the Fe-Pt films was ranging from 1.65 at% to 76.45 at% when the deposition potentials were changed from -1.0 V to -2.2 V vs Ag/AgCl in electrodeposition system at 353 K. Fe50Pt50/Fe2Pt98 multilayers were successfully electrodeposited from the ionic liquid system at 353 K by controlling the pulse electrodeposition potential. Current transients revealed that the nucleation of Fe50Pt50 layer was a three-dimensional instantaneous nucleation growth controlled by diffusion. Fe50Pt50/Fe2Pt98 multilayers of four-bilayer structure (FBS) were prepared with single-bath technique using pulse electrodeposition under potential control. The cross-sectional images of multilayers showed distinct layers with columnar structure. X-ray diffraction (XRD) pattern showed that the fct structure of Fe50Pt50/Fe2Pt98 multilayer had been obtained. Magnetic hysteresis loops showed that perpendicular coercivity values were increased from 153 Oe to 800 Oe with the increase of Fe50Pt50 layer thickness in FBS from 118 nm to 300 nm. FBS exhibited a magnetic anisotropic behavior. (C) 2013 The Electrochemical Society. All rights reserved.
