从材料、工艺和物理的角度来看,通过精确控制的纳米级制造技术获得用于超高密度硬盘驱动器(HDD)的量身定制的纳米结构自旋材料,以及对其纳米磁性的了解是必不可少的。通过RKKY相互作用(间接)和直接交换耦合(表现为铁磁(FM)/反铁磁(AFM)界面的交换偏置)人工控制铁磁层之间的交换耦合是人们非常感兴趣的,并在传统的简单FM材料中诱导新的调制自旋结构引起了极大的关注。尤其是在相邻两个软磁层之间具有强合成反铁磁(SAF)耦合的软磁底层(SUL),在FM层之间引入交换耦合的交换耦合层叠介质以及FM/AFM界面处的巨大交换各向异性从应用的角度来看引起了人们的极大关注。在本文的框架内,我们根据我们的最新结果,从直接和/或间接交换耦合的角度讨论了超固体、颗粒介质和自旋阀磁头的未来技术发展趋势。
Tailor-made nano-structured spin materials obtained by precisely controlled nano-scale fabrication technologies for use in ultra-high density hard disk drives (HDDs), as well as an understanding of their nanomagnetics, are essential from the view point of materials, processes, and physics. Artificial control of the exchange coupling among ferromagnetic layers through the RKKY interaction (indirect) and direct exchange coupling represented as the exchange bias at the ferromagnetic (FM)/antiferromagnetic (AFM) interface are of great interest and have received significant attention to induce new modulated spin structures in conventional simple FM materials. In particular, soft magnetic under layer (SUL) with strong synthetic antiferromagnetic (SAF) coupling between two adjacent soft magnetic layers, exchange coupled stacked media introducing exchange coupling between FM layers and giant exchange anisotropy at the FM/AFM interface have attracted significant attention from the view point of applications. Within the framework of the present paper, we discuss future technical trends for SUL, granular media and the spin-valve head from the viewpoint of direct and/or indirect exchange coupling based on our recent results.
