Abstract:

Magnetic skyrmions are topologically stable spin textures characterized by nanoscale dimensions, quasi-particle-like behavior, and low driving currents. They are widely regarded as the fundamental units for next-generation high-density information storage devices. Professor Yan Zhou's team has conducted a series of forward-looking research in three main aspects: new material systems for topological magnetic structures, generation/transportation/control of topological magnetic structures, and prototype device construction and design. Main contributions include: (1) Topological magnetic structures in (single-phase + artificially synthesized) antiferromagnetic, ferrimagnetic, and frustrated systems. In such systems, the helicity of magnetic skyrmions, as a new degree of freedom, can be manipulated by multiple fields, thereby enabling the design of novel functional devices. (2) Addressing key issues from an applied perspective, such as the magnetic skyrmion Hall effect, which leads to the annihilation of magnetic skyrmions as information carriers, resulting in the failure of spin topological functional devices. (3) Proposing important concepts based on magnetic skyrmions for racetrack memory, logic circuits, microwave source devices, and topological brain-like computing, all of which have become research hotspots.

Speaker Bio:

Yan Zhou graduated with a bachelor's degree from the University of Science and Technology of China in 2003 and obtained her Ph.D. from the Royal Institute of Technology in Sweden in 2009. She was selected as a national specially appointed young expert in 2015. Starting in 2016, she served as an associate professor at The Chinese University of Hong Kong (Shenzhen), and from 2020 to 2022, she served as the assistant dean responsible for scientific research at the Faculty of Science and Engineering. Since 2022, she has been a professor at The Chinese University of Hong Kong (Shenzhen). She has published over 100 JCR Q1 papers as the first author or corresponding author, with more than 12,300 citations and an H-index of 54. Professor Yan Zhou has long served as a reviewer for journals such as Review of Modern Physics, Nature, Nature Materials, Nature Physics, Nature Nanotechnology, and PRL. She has been invited to give talks at the American Materials Research Society, the American Physical Society, and the Chinese Physical Society, and has also been invited to serve as a reviewer for projects by the National Natural Science Foundation of China, the French National Research Agency, the German Science Foundation, the European Union, and the Shenzhen Science and Technology Innovation Commission.
