An international research team led by Assistant Professor Hang Chi from the Department of Physics at the University of Ottawa has published significant findings in Progress in Physics Reports, developing magnetically enhanced ultra-thin magnet materials. This breakthrough provides a new material foundation for creating more efficient electronic devices and quantum computers.

Traditional magnets are difficult to miniaturize for applications, while two-dimensional magnets at the atomic scale face limitations in operating at low temperatures. The research team innovatively combined ultra-thin magnets with topological insulator materials, significantly improving magnet performance. Experimental data show that this composite structure increases magnetic strength by 20% and expands the operating temperature range.
Professor Hang Chi stated, "It's like giving the magnet a boost. By combining materials, we enhance the magnet's performance without compromising its properties." The key to this technology lies in leveraging the unique conductive properties of electrons on the surface of topological insulators, effectively improving the magnetic stability of ultra-thin magnets.
Currently, these enhanced ultra-thin magnets demonstrate excellent performance at liquid nitrogen temperatures (77 Kelvin). The research team is working on testing more material combinations, aiming to achieve stable operation at room temperature, which would greatly expand their practical application prospects.
This technological breakthrough paves the way for developing smaller, more energy-efficient electronic devices. In the future, it may be applied to high-speed computing equipment, high-density data storage systems, and quantum information processing. The researchers note that this material design approach offers new directions for nanoscale magnet research.
