| 摘 要： | 钴基合金和铁基合金磁性纳米颗粒薄膜和纳米超晶格结构,由于具有较高的矫顽力和各向异性能,较小的粒子尺寸分布和能形成“单域”结构等特性,从而成为颇有潜力的高密存储介质。最近几年,人们竞相研究其制备方法,其中主要包括真空淀积法、液相化学合成法和离子注入法等,采用各种措施来提高存储介质的热稳定性和其他磁学性能,并取得巨大进展。

| Abstract: | Due to their higher coercivity (HC) and magnetocrystalline anisotropy (Ku), smaller size distribution and "single-domain" structures, Co-based alloy and Fe-based alloy magnetic nanoparticle thin films and superlattice structures have great potential application for extremely high density recording (EHDR) media, so people are eager to seek effective methods to fabricate magnetic nanoparticle thin films and superlattice structures and to take various measures to improve the thermal stability and other magnetic properties of recording media. Vacuum deposition techniques, solution phase chemical synthesis and ion implantation techniques etc are investigated.Great progresses have been made during the latest few years. |
