The studentship aims to design, produce and analyse synthetic layered magnetic structures in a parameterised way to control both magnetic and electrical properties. Thin films allow a very high degree of control, on the nanoscale, and can result in exceptional properties due to the designer combination of novel materials and the reduced dimensionality. The project will create bespoke test materials by combining selected metallic and insulating magnetic layers to create 'synthetic ferromagnetic materials' by sputtering. These synthetic materials would be patterned into two dimensional arrays using nanoscale lithography to create sample areas of very highly ordered and shaped nanomagnets, where the multilayer structures, the shape and spacing are well controlled. Structural analysis along with static and detailed high frequency electromagnetic behaviour would then be analysed. This will then be used to guide larger scale development. These high specification techniques have never been applied in this context before making the research truly novel.

该研究旨在以参数化的方式设计，生产和分析合成分层磁性结构，以控制磁和电性能。薄膜允许在纳米级上进行非常高程度的控制，并且由于新颖材料的设计者组合和降低的维度，可以导致特殊的性能。该项目将通过结合选定的金属和绝缘磁性层来创建定制的测试材料，以通过溅射创建“合成铁磁材料”。这些合成材料将使用纳米级光刻被图案化成二维阵列，以产生非常高度有序和成形的纳米磁体的样品区域，其中多层结构、形状和间距被很好地控制。结构分析沿着静态和详细的高频电磁行为，然后进行分析。这将用于指导更大规模的开发。这些高规格的技术在使研究真正新颖之前从未在这种情况下应用过。
