A CoNiFe film with saturation magnetic flux density (Bs) greater than 2.0 tesla (T) has been prepared for the first time as a soft magnetic film; the coereivity (Hc) of the film is less than 160 A/m (2.0 Oe). This success was achieved by formulating a new plating bath and operating conditions to form fine grains. The film has a low Hc of less than 160 A/m, a low saturation magnetostriction (λs) of approximately 10-6, and a high Bs of 2.0-2.1 T. The present invention is expected to contribute to accelerating the development of not only the technology of high-density magnetic recording but also the field of magnetic materials in general.
