Electrochemical preparation of CoNiFe films was investigated from the viewp
oint that the organic additives present in the plating bath are one of the
most important factors in obtaining soft magnetic materials. Soft CoNiFe fi
lms with B-8 = 1.2 to 2.0 T were obtained by plating in the presence of dif
ferent additives. The results demonstrated a strong influence of different
additives present in the electrolyte on current efficiency, electrode kinet
ics, alloy composition, anomalous order of composition, corrosion resistivi
ty, saturation magnetic flux density, coercivity, and stress in CoNiFe film
