On October 26, the College of Mathematics and Physics successfully held the tenth session of the "Xishu·Wuli" high-level academic lecture series at the Multi-Function Hall of the Gymnasium on the Changping Campus. The event featured an academic report by Professor Yu Guoqiang from the Institute of Physics, Chinese Academy of Sciences, titled "Topological Spin Memory Materials and Devices." The report was presided over by Wang Wei, Dean of the College of Mathematics and Physics, with nearly 200 teachers and students from the Changping Campus in attendance.
Professor Yu Guoqiang's report focused on frontier research in topological spin memory materials and devices. Spintronic devices based on the spin degree of freedom of electrons hold broad application prospects in information storage and processing. To realise high-performance devices, it is essential to explore smaller and more efficient magnetic information carriers and their control mechanisms, so as to overcome the bottlenecks in storage density and power consumption. Owing to their nanoscale size and ultra-low driving current density, topological magnetic structures known as skyrmions are regarded as ideal information carriers for future high-density, high-speed and low-power magnetic memory and logic devices. Professor Yu systematically presented the latest research achievements of his group in topological spin memory materials and devices, and provided an in-depth analysis of the key scientific challenges that remain to be addressed in this field.
During the interactive session, the attending teachers and students raised questions and engaged in active discussion. Professor Yu answered their research-related questions with patience and care, creating a lively and stimulating academic atmosphere.
The "Xishu·Wuli" high-level academic lecture series remains committed to building a high-level platform for academic exchange. It aims to help teachers and students stay abreast of disciplinary frontiers and emerging trends, sharpen their research thinking and enhance their research literacy through dialogue and critical inquiry, and inject strong momentum into the College's scientific innovation and high-quality talent cultivation.
