ABSTRACT:
A soft magnetic film includes a ferromagnetic layer. The ferromagnetic layer is laid over a non-magnetic substructure including ferromagnetic atoms. The uniaxial magnetic anisotropy may be established in the ferromagnetic layer. Since a magnetic property is not required in the substructure under the ferromagnetic layer, the soft magnetic film of this type may be utilized for purposes of wider variations.
