Exploring van der Waals magnetism in two-dimensional systems


  • Manh-Huong Phan ⋅ US University of South Florida, USA


Two-dimensional (2D) van der Waals (vdW) magnets are emerging as the cornerstone of a next-generation computing paradigm rooted in spintronics. Beyond their compactness, these magnets promise accelerated processing, reduced energy demands, and enhanced storage capabilities. However, to fully unlock their potential, precise control over their atomic-scale magnetism at room temperature is essential. In this context, we discovered strong and tunable room temperature ferromagnetism in atomically thin magnetic materials, especially in transition metal dichalcogenides (TMDs) and heterostructures, that have the potential to transform the fields of vdW spintronics, opto-spintronics, valleytronics, and quantum computation. I will explore the evolving opportunities and challenges within 2D van der Waals (vdW) magnet research. I'll introduce an innovative method for manipulating 2D magnetism using light, and demonstrate how we can harness this optical control to modulate thermally driven spin currents through the spin Seebeck effect, giving rise to the emerging field of Opto-Spin-Caloritronics.
