Exfoliation and optical properties of S = 1 triangular lattice antiferromagnet NiGa2S4
Abstract Two-dimensional (2D) van der Waals (vdW) materials have been an exciting area of research ever since scientists first isolated a single layer of graphene.Single layer magnetic materials can provide a pathway for vdW heterostructures with magnetic properties.While most of the magnetic vdW materials exhibit ordering transitions in the bulk,
