FeCoZr soft magnetic films with amorphous structure were electrodeposited onto ITO conductive glass substrates from the electrolytes with different composition and deposition potential. The factors which affect the deposit composition were discussed. The in-plane uniaxial magnetic anisotropy of film intensively depended on the concentration of boric acid. The coercivity of thin films decreased significantly with the composition gradient of doping Zr element. The ferromagnetic resonance frequency was as high as 3.4 GHz. Therefore, these films have a wide range of applications in the high-frequency field. (C) 2012 Elsevier B.V. All rights reserved.
