Realising 3D Artificial Spin-Ice Systems using Two-Photon lithography and Line-of-Sight Deposition

“今天，绝大多数数字信息都存储在计算机硬盘驱动器（HDD）上。在过去的20年里，通过减少存储数字信息的磁性特征的尺寸，密集的研究工作使得硬盘的面密度能够满足社会的需求。这种技术的一个显著缺点是，所有的纳米磁铁都位于磁盘上的一个平面上，有效地限制了可以存储的信息量。最近在制造技术上的进步已经允许生产三维纳米结构的选择几何形状。在卡迪夫，我们最近安装了一个尖端的3D光刻系统，能够生产分辨率为200nm的3D模板。该项目的学生将接受高级3D制造技术，磁性表征和高分辨率电子显微镜的培训。对不同几何形状、尺寸和材料的三维磁性纳米结构进行基础研究。学生还将受益于定期访问欧洲的工业合作伙伴。”

"Today, the vast majority of digital information is stored on computer hard disk drives (HDD). Intense research efforts over the past 20 years has allowed the areal density of the HDD to scale with societies needs by reducing the size of the magnetic features that store digital information. A significant disadvantage of such technologies is that all of the nano-magnets sit in one plane on the disk, effectively limiting the amount of information that can be stored.Recent advances in fabrication techniques have allowed the production of three-dimensional nanostructures of chosen geometry. Here at Cardiff, we have recently installed a cutting-edge 3D lithography system capable of producing 3D templates at a resolution of 200nm.The student on this project will receive training in advanced 3D fabrication techniques, magnetic characterisation and high-resolution electron microscopy. Fundamental studies will be carried out upon 3D magnetic nanostructures of different geometry, dimensions and material. The student will also benefit from regular visits to industrial collaborators in Europe."
