报告摘要：

The foundational understanding of magnetism has been greatly enhanced through the application of the synchrotron radiation generated x-rays. While x-ray diffraction has been around for more than a centenary, magnetic resonant absorption was only established three decades ago. Spectroscopic information is obtained by monitoring the reaction of core-level electrons to bombardment by high-intensity x-rays. This can be used to quantitively determine atomic spin and orbital moments. In this talk, I will explain how the x-ray magnetic circular dichroism (XMCD) technique has enabled our research into various magnetic and quantum materials that might be exploited in applications like memory devices.

报告人简介：

Professor Wenqing Liu, RAEng/Leverhulme Trust Senior Fellow, academic lead with over 15 years’experience in UK higher education across Russell Group and London institutions. She was the first female Head of the Department of Electrical Engineering and Electronics (EEE) at the University of Liverpool in its 150-year history, where she led the curriculum reform, business-planning, and people development.

Professor Liu's research spans condensed matter physics, quantum materials and devices with international recognition. She brings specialist expertise in semiconductors, materials strategy, sustainability drivers, and architectures vital to modern device scaling and emerging fabrication. Her work informs the future of epitaxy manufacturing, Al-driven materials discovery, and automation, contributing to R&D roadmaps. Professor Liu also provides executive-level insight into higher education, advising on institutional strategy, governance reform, and international articulation. She supports benchmarking, de-risking of transnational ventures, and academic transformation through change design, risk analysis, and team coaching. She holds several positions of trust within the wider research community, including research assessment for the UK EPSRC, STFC, MRC, Swiss SNSF,  NWO, and India Alliance, serving as panel chair at the UK Diamond Light Source, and as a member of the advisory board of the UK NAME programme.
