德国与挪威科研团队在磁性材料动力学领域取得重要进展，首次实现了对斯格明子晶格熔化过程的实时观测及单粒子形态的同步调控 1。这一发现揭示了二维斯格明子晶格的新行为特性，相关成果已发表于《自然·纳米技术》2025年第20卷第10期（页码1405），DOI编号为10.1038/s41565-025-01977-2 1。该研究由约翰内斯·古腾堡美因茨大学与挪威科技大学合作完成，核心参与者包括来自NTNU量子自旋电子学中心的Asle Sudbø等多位学者 1。
这项突破性工作证实了单个斯格明子的形状和大小可被动态改变，这被视为开发低能耗、高密度数据存储系统及模拟人脑运作机制计算机的关键一步 1。通过操控这些微型磁涡旋，研究人员有望推动下一代量子技术及更小型节能计算设备的发展 1。
Researchers from Johannes Gutenberg University Mainz in Germany and the Norwegian University of Science and Technology (NTNU) have achieved a significant breakthrough in magnetic nanotechnology by capturing, for the first time, the real-time melting process of a magnetic skyrmion lattice 1. Published in Nature Nanotechnology in October 2025, the study demonstrates not only the dynamic observation of these structures but also the ability to synchronously alter the shape and size of individual skyrmions during the melting phase 1. This work, which spans research locations in Mainz, Germany, and Trondheim, Norway, marks a pivotal step in understanding two-dimensional skyrmion lattice dynamics 1.
The team, including key figures such as Asle Sudbø, head of NTNU’s QuSpin center for quantum spintronics, identified new behavioral characteristics of skyrmions through this precise control 1. By manipulating these tiny magnetic vortices at a fundamental level, the researchers aim to lay the groundwork for developing low-energy, high-density computing systems that function more like the human brain 1. The potential applications extend to creating smaller, more energy-efficient data storage solutions and advancing quantum technologies 1.
