Abstract
The magnetic laminated film includes magnetic films having smooth surfaces. The method of manufacturing the magnetic laminated film comprises the steps of: forming a magnetic film including Fe and Co; smoothening a surface of the magnetic film; forming a discontinuous film, which is composed of a magnetic material or an insulating material and which has a thickness to form a discontinuous film, on the smooth surface of the magnetic film; and repeating the above described steps to laminate a plurality of the magnetic films.
