New Developments on Chromium Trihalides 2D Ferromagnets

David Soriano

The discovery of 2D ferromagnets in 2017 has opened new ways to explore novel physical phenomena at the nanoscale. In the first part of my talk, I will briefly discuss the recent advances in chromium trihalides, from fundamentals to applications.[1] In the second part, I will focus on our recent work regarding the role of Coulomb interactions in the intralayer exchange, the electrical tunability of interlayer magnetism in bilayer CrI3,[2] and the exchange proximity effects in van der Waals heterostructures containing chromium trihalides.[3,4] [1] Magnetic Two-Dimensional Chromium Trihalides: A Theoretical Perspective.
