The propagation of precessional excitations of ordered spins in magnetic materials - so-called spin waves - in complex micromagnetic landscapes forms basis of magnonics - the recently emerged and rapidly developing field of magnetism. The ultimate idea is to implement spin waves within signal and data processing devices that would be faster, smarter and more energy efficient than those based on semiconductors. In this project, you will design and predict performance of novel spin wave ("magnonic") devices using advanced numerical modelling tools. The best designs will then be within prototype devices that will be fabricated using advanced lithography tools and tested using microwave measurements and time resolved microscopy.

磁性材料中有序自旋的进动激发-所谓的自旋波-在复杂的微磁性景观中的传播形成了磁子学的基础-最近出现并迅速发展的磁性领域。最终的想法是在信号和数据处理设备中实现自旋波，这将比基于半导体的设备更快，更智能，更节能。在这个项目中，您将使用先进的数值建模工具设计和预测新型自旋波（“磁振子”）器件的性能。最好的设计将在原型设备中使用先进的光刻工具制造，并使用微波测量和时间分辨显微镜进行测试。
