Soft magnetic thin films with high saturation magnetic flux density (Bs), high electrical resistivity (?), and low coercivity (Hc) are used as core materials of high-density recording heads. Electroless deposition method is a promising method for fabrication of magnetic thin films with such benefits as capability of uniform coatings fabrication on the substrates with fine and complex geometries. This work describes the most recent findings of our rigorous investigation on the effects of electroless bath conditions on the film composition, crystal structure, surface morphology, and magnetic properties. This report shows how the composition and crystal structure of the fabricated films can be precisely controlled only by optimizing the bath condition and not changing the solution composition, so that desirable magnetic properties can be reached.
