Quantum magnetism under extreme environment

The research on (quasi) 2D magnetism propelled rapidly since the first experimental discovery of atomically thin magnets in 2017. Since the magnetic properties of bulk (quasi-2D) crystals serve as a basis for the understanding of magnetic phenomenon in reduced dimensions (true 2D limit), a profound knowledge and understanding of these compounds is needed at the quasi-2D level, especially considering that magnetic mono and bilayers of a wide range of 2D magnets have now become accessible. In this talk, I will present and discuss our recent findings in tuning the magnetic properties of quasi-2D layered van der Waals magnets by photoexcitation, proton irradiation, and the application of pressure.
