Ferromagnetism created from non-ferromagnetic vdW heterostructures

ORAL

Abstract

Intrinsic long-range ferromagnetic order has recently been discovered in two-dimensional atomic crystals. However, the prospect of 2D magnets remains largely hindered by the scarcity of 2D ferromagnets with limited diversity in magnetic attributes. In this context, creative ways to bring forth ferromagnetism from non-ferromagnetic 2D materials are attractive and profitable for both fundamental physics and device applications. In this talk, I will show you the possibility of such creation based on our magneto-optical study of vdW heterostructures and discuss the underlying material physics. Our work paves the new path to harvest 2D ferromagnetism.
