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.

自从十年初以来，数据量一直在大幅度上升，并且现在大数据和物联网正在加剧，现在将更快地上升。拓扑旋转孤子子在磁性数据存储和信息处理中的应用是对这种不断增长的需求的潜在解决方案。为了实现这一愿景，对未来设备的量身定制设计需要对旋转孤子静态和动态属性的详细理解。在该项目中，我们将开发用于传输电子显微镜（TEM）中自旋纹理动力学高分辨率磁性表征的平台，并结合运输测量。悉尼大学的高级显微镜和电子设备制造和表征方面具有世界领先的专业知识，为拟议的研究提供了理想的环境。这项工作的结果将是有关自旋纹理如何在纳米尺度上动态行为的首次体积敏感的研究。
