摘要： PURPOSE: To improve the magnetic characteristic of an Fe
x N film as a vertically magnetizable film by depositing at least one nonmagnetic conductive film as an underlying film on a substrate thereby forming the Fe
x N film thereon.
CONSTITUTION: The nonmagnetic substrate 1 is housed in an RF sputtering device and an underlying film and the Fe
x N film are continuously sputtered by a sputter target 2. A material with which the nearest inter-atom distance (DCA) is 2.5W3.2Å, for example, elements such as V, Ru, Zn W, etc. and the conductive nitride, oxide, etc. thereof are used as the conductive underlying film. The C-axis of the Fe
x N film is considered to be oriented in the direction perpendicular to the film plane when such underlying film is deposited on the substrate. The upper limit value of Bs to be formed as the vertically magnetizable film is thus made ≥7000G and the magnetic characteristic of the Fe
x N film is improved.

6 Si is directly sputtered thereon without bringing the thin film into contact with air and oxidizing the surface of the thin metallic film to form the protective layer 3. Ruggedness having 200W500Å depth exists on the surface when the film 2 is of the vertically oriented columnar crystal. The holes having ≤10Å depth exist also on said surface and the B of the small atomic size is liable to intrude into such ruggedness or holes and since the B has good affinity to the metallic atoms, the film 3 sticks securely to the magnetic layer 2 thereby providing the dense layer having the excellent wear resistance and lubricity.
