摘要:
A method for producing a permanent magnet film having the performance capability as a permanent magnet, characterized in that it comprises converting a powder of a permanent magnet material to the form of an aerosol and spraying the aerosol to an article due to have the permanent magnet film thereon, to thereby form the permanent magnet film; and the above method, characterized in that the powder of a permanent magnet material comprises a magnet metal powder, a ferrite compound powder, a mixture of a magnet metal powder and a ferrite compound powder, a mixture of a magnet metal powder and a polymer material powder, a mixture of a ferrite compound powder and a polymer material powder, or a mixture of a magnet metal powder, a ferrite compound powder and a polymer material powder; and a permanent magnet film produced by the method. The method allows the production of a permanent magnet film having a thickness expected for a thin magnetic film in the near future and exhibiting high magnetic characteristics, with high efficiency at a low cost.
