My research interest originates from the interaction processes between photons and magnetism, which serves as a foundation for developing methodologies to explore the underlying physics of magnetism. My work focuses on investigating the electronic and magnetic structures in condensed matter from the perspective of X-rays. This includes studying the origins of magnetism at the atomic scale, magnetic interactions at the microscopic scale, magnetic ordering at the mesoscale, magnetodynamics on ultrafast timescales, and the interplay between magnetism and charge or lattice degrees of freedom.
The Magnetic Scattering and Spectroscopy Laboratory ( MSSL ) employs electromagnetic waves across a wide frequency range ( radiofrequency – microwave – ultraviolet – soft X-rays – hard X-rays ) to probe magnetism in quantum materials. Leveraging the unique advantages of synchrotron X-rays, including high flux, continuously tunable energy, controllable polarization, and ultrafast time resolution, we have developed novel X-ray-based techniques to study magnetism and continue to explore new mechanisms of photon-magnetism interactions.Our primary experimental approaches for investigating quantum materials include X-ray magnetic scattering ( such as soft X-ray resonant scattering, hard X-ray non-resonant scattering, and magnetic surface scattering ) and magnetic spectroscopy ( XMCD / XMLD ). We maintain close collaborations with magnetic beamlines at synchrotron facilities worldwide. The materials systems currently under study encompass topological magnetic materials, noncollinear magnetic materials, magnetically frustrated systems, ferroelectric materials, chiral magnets, two-dimensional magnetic materials, and spin states in topological electronic structures of quantum materials.
