This project aims to investigate the fundamental properties (magnetic structure, surface topology, dynamics and interaction with external stimuli) of topological spin systems. Unconventional topological spin structures at the nanometre scale, such as skyrmions in chiral spin systems, could be used in ultra-low energy electronics and high density data storage. In particular, multi-ferroic skyrmion materials could directly control skyrmions through an external electric field, which makes them ideal for nanoelectronics and data storage for IT applications. This project will create and investigate skyrmion materials as the basis for next generation computer and information technology in Australia.

本项目旨在研究拓扑自旋系统的基本性质（磁结构、表面拓扑、动力学和与外部刺激的相互作用）。纳米尺度下的非传统拓扑自旋结构，如手性自旋系统中的Skyrmion，可以用于超低能电子学和高密度数据存储。特别是，多铁性skyrmion材料可以通过外部电场直接控制skyrmion，这使得它们成为IT应用中纳米电子和数据存储的理想选择。该项目将创建和研究Skyrmion材料，作为澳大利亚下一代计算机和信息技术的基础。
