PURPOSE:To obtain a magnetic thin film which is excellent in magnetic characteristics and durability, and moreover, is theremally stable by a method wherein Fe, Al and Si, whose wt% have been respectively specified, are used as a constituent composing of the main component of the magnetic thin film and N2, whose wt% has been also prescribed in the same manner as the above-mentioned respective constituent, is made to be contained in the main component. CONSTITUTION:This main component is composed of Al of 2-10wt%, Si of 3- 16wt% and the remnant, Fe, and N2 of 0.005-6wt% is made to contain in the main component. A magnetic thin film for VTR and so forth is manufactured using the abovementioned compound. When N2 is made to contain in the main component of the magnetic thin film in such a way, its magnetic permeability in 1MHz reaches as high as more than 5,000 compared to a magnetic thin film of a main component, wherein N2 has not been contained, and its Vickers hardness is also increased as high as more than 1,000. Moreover, a magnetic thin film, whose saturation magnetic flux is 11,000 Gauss and coercive force is also as high as 0.3Oersted, is obtained by such a way. |
