Topotactic Control of Magnetism in Multiferroic and Skyrmion Materials

多铁性和天离子材料的工程和利用目前正受到极大的关注，因为它们为纳米电子和高密度数据存储的基础研究和未来的技术应用提供了大量令人着迷的现象。应用的一个瓶颈是对单相材料中磁性的精确控制。该项目预计将深入了解新的拓扑定向磁性材料的合成和性能。利用拓扑定向转变(材料中可逆的化学计量比变化导致晶体结构的变化)可以被视为设计未来纳米电子学中可控的多铁性和Skrrmion主体材料的新概念。

The engineering and utilisation of multiferroic and skyrmion materials is currently receiving tremendous attention as they offer a plethora of fascinating phenomena for fundamental research and future technological applications in nanoelectronics and high density data storage. One bottleneck for applications is the precise control of magnetism in single phase materials. The project is expected to deliver insight into synthesis and properties of new topotactic magnetic materials. The utilization of topotactic transitions (reversible stoichiometric changes in materials that lead to changes in the crystal structure) can be seen as a new concept for designing controllable multiferroic and skyrmion host materials for future nanoelectronics.
