Electrodeposited CoNiFe soft magnetic films with high Bs were investigated for use as head core materials. It was found that a film consisting of an fcc phase structure with low Fe content has low magnetostriction of +2∼+6 × 10-6. When the film composition was fixed at Co62Ni12Fe26, the operating conditions for obtaining soft magnetic properties were optimized It was found that soft magnetic thin films composed of fine crystals 10-15 nm in diameter were obtained in conditions of low pH (< 3.0) and low current density (< 40 mAcm-2). In these operating conditions, a current efficiency of less than 80% with hydrogen evolution during the CoNiFe deposition was confirmed to be one of key factors for obtaining soft magnetic CoNiFe films with a suitably high Bs value. A typical Co62Ni12Fe26 film had the following properties. Bs=2.0 T, Hc=1.7 Oe, and λs=+4.9×10-6.
