Preparation of nanoparticle recording media for next-generation magnetic recording

在这项研究中，我们致力于开发用于下一代记录介质的纳米颗粒磁记录介质。为此，采用一种新的溅射方法制备了具有L10晶相结构和纳米颗粒组装结构的FePT合金薄膜。结果发现，在300℃左右的衬底温度下，可以生长出具有预期结构和磁性能的铁铂薄膜。它们被认为是具有作为纳米颗粒磁记录介质的非常高潜力的薄膜。

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.
