On October 22, the College of Mathematics and Physics successfully held the sixth session of the "Xishu·Wuli" high-level academic lecture series at the Lixue Lecture Hall on the Changping Campus. The event featured Professor Song Cheng from the School of Materials Science and Engineering at Tsinghua University, who delivered an academic report on "altermagnets." The lecture attracted over 260 participants, including undergraduate students, graduate students, and faculty members from the Changping Campus. The session was presided over by Professor Wang Wei, Dean of the College of Mathematics and Physics.

Professor Song Cheng provided an accessible introduction to the concept and research background of altermagnets. He then focused on three typical altermagnets—RuO₂, Mn₅Si₃, and CrSb—to elaborate on the progress of scientific research in this field. Additionally, he shared the journey of technological innovation undertaken by his team and their latest research achievements. During the Q&A session, Professor Song patiently addressed questions from the audience.

This lecture highlighted the latest advancements in magnetic materials research, offering faculty and students insights into cutting-edge developments and deepening their professional understanding. It also effectively stimulated interdisciplinary thinking and innovative thinking. The "Xishu·Wuli" lecture series will continue to bring the latest scientific discoveries and technological achievements to the academic community, driving talent development and scientific innovation through exposure to frontier research.
