Research Interests

Our major interest lies in magnetic materials with strong correlation. We are particularly interested in discovering new materials and leading original researches. Our current researches consist of the following three topics: the discovery of new materials with strong correlation; the basic and applied researches on two-dimensional magnetic van der Waals materials; the exploration of new phenomena with spin-orbit coupling and topological physics in magnetic materials. In order to carry out these research goals, we start from synthesizing new materials to characterizing physical properties and eventually to studing structure and dynamics using X-ray and neutron scattering. Among many achievements our group has made over the years, we would like to mention two most recent works: the discovery of magnetic van der Waals materials; full understanding of magnon-magnon/phonon coupling.
