Preparation of nanoparticle recording media for next-generation magnetic recording

在这项研究中，我们的目标是开发下一代记录介质的纳米颗粒磁记录介质。为此，使用一种新的溅射方法来制备具有L10晶相和纳米颗粒组装结构的FePt合金薄膜。结果表明，在300 ℃左右的衬底温度下，可以生长出具有目标结构和磁性的FePt薄膜。它们被认为是作为纳米颗粒磁记录介质具有非常高潜力的薄膜。

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.
