Correlation of the transport properties and spin texture of magnetic bubbles by in-situ TEM

自本世纪初以来，数据量一直在大幅上升，随着大数据和物联网的兴起，数据量的增长速度将更快。拓扑自旋孤子在磁数据存储和信息处理中的应用有望成为这一日益增长的需求的潜在解决方案。为了实现这一愿景，需要详细了解自旋孤子的静态和动态特性，以便为未来的设备量身定制设计。在这个项目中，我们将开发一个平台，结合输运测量，在透射电子显微镜（TEM）中对自旋织构动力学进行高分辨率磁表征。悉尼大学在先进的显微镜和电子设备制造和表征方面拥有世界领先的专业知识，为拟议的研究提供了完美的环境。这项工作的结果将是有史以来第一次对纳米尺度下自旋纹理动态行为的体积敏感研究。

Data volumes have been on a major upturn since the beginning of the decade and are about to rise even faster now that Big Data and the Internet of Things are ramping up. The application of topological spin solitons to magnetic data storage and information processing is anticipated to be a potential solution to this ever-increasing demand. In order to achieve this vision, a detailed understanding of the spin solitons static and dynamic properties is required for a tailored design of future devices. Within this project, we will develop the platform for high-resolution magnetic characterisation of spin texture dynamics in the transmission electron microscope (TEM) in combination with transport measurements. With its world-leading expertise in advanced microscopy and electronic device fabrication and characterisation, the University of Sydney, provides the perfect environment for the proposed research. The outcome of this work will be the first ever volume-sensitive investigation into how spin textures behave dynamically at the nanometer scale.
