To obtain amorphous Fe-B-plated films with soft magnetization, the effech of a combined complex agent of potassium sodium tartrate (KNaC_4H_4O_6・4H_2O) and ammonium sulfate ((NH_4)_2SO_4) on the film properties was investigated. Soft magnetic films with coercivities of less than 4 Oe were obtained by using a bath composition of KNaC_4H_4O_6・4H_2O=600mmol/L and (NH_4)_2SO_4=80mmol/L. These soft films also exhibited large magnetostriction of 26×10^<-6>, suggesting that the use of the combined complex agent is very effective for obtaining FeB amorphous films that have soft magnetic properties and large magnetostriction smultaneously. Change in composition of films along their thicknesses is considered to be responsible for the magnetic softening of FeB-plated films.
