项目摘要
In order to store all of the digital information in the world, HDD with huge capacity an high recording density are necessary. In this study, synthesis of a patterned media using hexagonal ferrite thin films with self assembled nano-dot structure has been tried for future high density recording media. Two under-layer, which are Si-Al layer and Au nano-dot layer have been used for the under layer of hexagonal ferrite layer. Ferrite layer is non-magnetic when it is amorphous. The crystallization temperature of ferrite layer on metal under-layer is much lower than that of non metallic under layer. The idea of this research is nano-dot crystallization of hexagonal ferrite layer with self-assembled metal nano-dot area. The MFM images show that hexagonal ferrite layer seems to be crystallized on Au nano-dot parts and other area is still amorphous and non-magnetic.
为了存储世界上所有的数字信息,需要具有大容量和高记录密度的HDD。在这项研究中,合成的图案化的媒体使用六角铁氧体薄膜与自组装纳米点结构已被尝试为未来的高密度记录介质。六方晶系铁氧体层的底层采用Si-Al层和Au纳米点层。当铁氧体层是非晶时,它是非磁性的。金属衬层上铁素体层的晶化温度远低于非金属衬层。本研究的想法是在六方晶系的铁氧体层上自组装金属纳米点区域进行纳米点晶化。MFM图像显示,六角铁氧体层似乎是结晶的Au纳米点部分和其他区域仍然是非晶和非磁性。
