Symposium QM01-Novel Approaches to Manipulate and Detect 2D Magnetism in van der Waals Quantum and Topological Materials

The discovery of 2D magnets has rapidly generated remarkable breakthroughs for intriguing fundamental science and potential next-generation applications. In this context, numerous van der Waals magnets have been discovered and many routes were employed to manipulate and control their spin states. Moreover, several sophisticated experimental and theoretical methods have been developed and applied to detect their magnetic ordering. This symposium explores the recent advances in manipulating magnetism through moiré engineering, twisting, gating, proximity effect, intercalation, photoexcitation, and pressure. This symposium also covers the experimental (scanning magnetic probes, scanning SQUID, scanning NV center microscopy, etc.) and theoretical methods (e.g. higher-order spin interactions, etc.) to fully understand such strongly correlated magnetism. The material systems include atomically thin chromium trihalides, metallic magnets, chalcogen-based van der Waals magnets, twisted magnets/graphene, magnetic topological insulators, and Weyl semimetals. This symposium's primary goal is to bring together both experimentalists and theoreticians investigating the physics, chemistry, materials science, and engineering aspects of magnetic quantum materials. This symposium will enable researchers to receive a more in-depth perception of this emerging field and its grand challenges and opportunities in the field of quantum magnetism.

Topics will include:

  • Twisted 2D Magnets, Moire Engineering, the interplay between magnetism and topology
  • Gate Tunable 2D Magnetism and Proximity Effects
  • Effect of Intercalation on 2D Magnetism
  • Ultrafast Manipulation of 2D Magnetism, and Pressure Controllable 2D Magnets
  • Advanced experimental probes to directly characterize 2D magnetism
  • Theoretical developments and computational methodologies of Quantum Magnets
