Since needs for higher magnetic recording density have accelerated to prepare soft magnetic films with a higher saturation magnetic flux density, basic information on the magnetic properties of electrodeposited CoNiFe must be prepared, as must quenched CoNiFe ribbons. Electrodeposited CoNiFe films were prepared in a lower metal ion concentration permalloy bath, relatively independent of current density. When the NiSO<sub>4</sub> concentration was fixed at 0.2mol dm<sup>-3</sup> and the (CoSO<sub>4</sub>+FeSO<sub>4</sub>) concentration was varied, the Ni content was controlled. Co and Fe content were also controlled by changing the ratio of CoSO<sub>4</sub> and FeSO<sub>4</sub> concentration. The magnetic properties, coercivity, saturation magnetic flux density, and magnetostriction of ternary CoNiFe thin films were formed.
