Abstract

Co-Fe soft magnetic thin films with high-saturation magnetic flux density Bs were prepared by electrodeposition. The Bs value of the Co-Fe alloy films deposited from the conventional cell system is lower than that of bulk alloys. With the use of a separated compartment dual cell system, the Bs value of the Co-Fe alloy films was reached the same as that of bulk alloy. The coercivity Hc values were higher than 12 Oe; however, the Hc value could be lowered to 8 Oe by annealing in vacuum with an applied magnetic field. It is suggested that decreasing Hc of the films by annealing is caused by relaxation of lattice distortion. In addition, the high-Bs Co-Fe films show good corrosion resistance.
