Abstract
A soft magnetic multilayer film is manufactured by an electroplating process using an electrolyte containing metal ions. The soft magnetic multilayer film includes soft magnetic layers composed of elements, and deteriorated-soft magnetic layers composed of the same elements and alternating with the soft magnetic layers. The soft magnetic layers are preferably different in composition from the deteriorated-soft magnetic layers. In addition, it is preferable that the metal ions contained in the electrolyte include at least two of Ni ion, Co ion, and Fe ion.
