摘要:
PURPOSE: To improve the magnetic characteristic of a vertically magnetizable Fe
x N film by depositing at least one intermediate film layer between a high permeability magnetic film and the Fe
x N film.
CONSTITUTION: A nonmagnetic substrate 1 is housed in an RF sputtering device and the high permeability film, intermediate film and Fe
x N film are continuously sputtered by a sputter target 2. The material of which the average nearest inter-atom distance (DCA) is 2.5W3.5Å, for example, elements such as V, Ru, Zn W etc. and the metallic nitride and metallic oxide thereof are used as the material for the intermediate film. The C-axis of the Fe
x N film is oriented perpendicularly to the film plane when such intermediate film is intervened by which the upper limit value of Bs to be formed as the vertically magnetizable film is made as high as ≥7,000G and the magnetic characteristic of the Fe
x N film is improved.
