Current status and perspectiveof magnetic van der Waals materials research

The discovery of graphene in 2004 took the scientific community by surprise and virtually transformed the research landscape by creating a then-new field of 2dmaterials. However, despite the unique properties of many van der Waals materials since discovered, it has certain limitations in terms of exploring novel and new physical properties. Magnetism is a case in point. Until a couple of groups and I started to work on the much-neglected magnetic van der Waals materials, virtually nothing was known about it. However, with a series of publications, including those from my group, this field of magnetic van der Waals materials has become a fast emerging field in materials science. In this presentation, I would like to take you through the intellectual journey I made since 2010 and eventually discovering a novel quantum spin-entangled exciton NiPS3more recently. I will end my talk by giving a personal view of prospects for future research.
