In a recent collaboration between the High Magnetic Field Center of the Hefei Institutes of Physical Science of Chinese Academy of Sciences, and the University of Science and Technology of China, researchers introduced the concept of the topological Kerr effect (TKE) by utilizing the low-temperature magnetic field microscopy system and magnetic force microscopy imaging system supported by the steady-state high magnetic field experimental facility.
The findings, published in Nature Physics, hold significant promise for advancing our understanding of topological magnetic structures.
Originating in particle physics, skyrmions represent unique topological excitations found in condensed matter magnetic materials. These structures, characterized by their vortex or ring-like arrangement of spins, possess non-trivial properties that make them potential candidates for next-generation magnetic storage and logic devices.
