| Research Abstract |
In this study, we aimed at the development of nanoparticle magnetic recording media for next-generation recording media. For the purpose, a new sputtering method was used to prepare a FePt alloy thin film having the structures of L10 crystal phase and nanoparticle-assembly. As a result, we found that the FePt thin films with aimed structures and magnetic properties have been grown at the substrate temperature of about 300 ℃. They are considered as a thin film having very high potential as a nanoparticle magnetic recording medium.
