PROCESS FOR PRODUCTION OF MAGNETIC THIN FILM, MAGNETIC THIN FILM, AND MAGNETIC MATERIAL |
摘要 |
The present invention provides a process for production of a magnetic thin film which has insulation properties, serves as a permanent magnet, and has improved residual magnetization in comparison with prior arts, the magnetic thin film, and a magnetic material. When a magnetic thin film 3 is formed, an external magnetic field with a predetermined intensity is applied to a coating liquid containing magnetic particles containing epsilon-type iron-oxide-based compounds which have insulation properties and which serve as a permanent magnet, and the coating liquid is let cured in order to form the magnetic thin film 3. Accordingly, the magnetic particles containing the epsilon-type iron-oxide-based compounds can be fixed while being oriented regularly in a magnetization direction. This realizes the process for production of the magnetic thin film 3 which has insulation properties and which serve as a permanent magnet, the magnetic thin film 3, and a magnetic material 1. |
