Manufacturing Magnetic Nano Structures

复杂的磁性纳米结构可以通过光刻从磁流体中有效地制备出来，并允许新的纳米级几何结构、性质和应用。我们提出了一种新一代的磁流体[1]，它具有高度有序的六角铁氧体纳米片悬浮在乙二醇中，可以通过双光子光刻进行局部聚合，生成具有嵌入磁性的高密度和复杂的三维纳米结构。这些具有灵活几何结构和磁性的未知纳米结构是在加的夫开发的，随后可能会产生新的铁磁自旋织构，形成直接由悬浮制造的下一代器件架构的基础。学生将接受利用工程学院先进的制造和表征设施进行纳米材料合成的培训。学生还将接受尖端高分辨率三维光刻、扫描探针显微镜和磁学方面的培训，并发展器件制造/表征方面的专家级知识。

Complex magnetic nanostructures can be effectively fabricated from ferrofluids via photolithography and allow for novel nano-scale geometries, properties, and applications. We propose a new generation of ferrofluids [1] with highly ordered Barium Hexaferrite nano-platelets suspended in ethylene glycol which can be locally polymerized by two-photon lithography and create highly dense and complex three-dimensional nanostructures with embedded magnetic properties. These unexplored nanostructures with flexible geometries and magnetic properties are developed in Cardiff and subsequently could lead to novel ferromagnetic spin textures forming the basis of next generation device architectures, directly manufactured from suspension. The student will receive training on nano-material synthesis utilizing the advanced manufacturing and characterisation facilities at the School of Engineering. The student will also be trained in cutting-edge high-resolution 3D-lithography, scanning probe microscopy, and magnetometry and develop expert level knowledge in device fabrication/characterisation
