Symposium QT06—Recent Developments on the Properties of Emergent Layered 2D Quantum Magnetic Materials and Heterostructures

The discovery of magnetic 2D materials in 2016 (antiferromagnet) and 2017 (ferromagnets) has created widespread research excitement in the recent past. Exceptional properties led to the unprecedented experimental and theoretical explorations of 2D magnetism. These materials have emerged as ideal solid-state platforms, in which the structural and magnetic order strongly couple. 2D magnets also present unique routes for controlling magnetic order through electrical gating, stacking, and heterostructure composition. Furthermore, it offers an exciting new opportunity for the seamless integration of 2D magnets with dissimilar electronic and photonic 2D crystals. Therefore, it is anticipated that 2D magnets will open extraordinary opportunities for a plethora of designer quantum heterostructures with previously inaccessible magneto-optical and magnetoelectric properties.

Of particular importance, this symposium focuses on the recent advances in the design and fabrication of new 2D magnets and their heterostructures; their magneto-optical and magnetoelectric properties; novel techniques in characterization of 2D magnets; and theoretical developments. 2D magnets include atomically thin chromium trihalides, chalcogen-based van der Waals magnets, twisted bilayer 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. With a mix of young scientists and established leaders in the field as invited and joint keynote speakers, the symposium will capture the new and most recent developments in the field of quantum magnetism and simultaneously enable researchers to receive a more in-depth perception of this emerging field and its grand challenges and opportunities.
