Manufacturing Magnetic Nano Structures

复杂的磁性纳米结构可以通过光刻技术从铁磁流体中有效地制造出来，并允许新的纳米级几何形状、性质和应用。我们提出了一种新一代铁磁流体[1]，它由高度有序的六铁钡纳米片悬浮在乙二醇中，可以通过双光子光刻技术进行局部聚合，并产生具有嵌入磁性的高密度复杂的三维纳米结构。这些未开发的具有柔性几何形状和磁性质的纳米结构是在卡迪夫开发的，随后可能导致新的铁磁自旋纹理形成下一代设备架构的基础，直接由悬浮液制造。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3d光刻，扫描探针显微镜和磁强计的培训，并在设备制造/表征方面发展专家级知识

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
