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,必须具有较高记录密度的HDD。在这项研究中,使用六角形铁氧体薄膜与具有自组装的纳米点结构的培养基合成,以用于将来的高密度记录介质。两个层层和Au纳米点层已用于六边形铁氧体层的下层。非晶子时铁液层是非磁性的。金属层上铁氧体层的结晶温度远低于非金属下层的结晶温度。这项研究的想法是具有自组装金属纳米点区域的六角铁素体层的纳米点结晶。 MFM图像表明,六边形铁氧体层似乎在AU纳米点零件上结晶,而其他区域仍然是无定的,也是非磁性的。
