Viewpoint: Opportunities and challenges of two-dimensional magnetic van   der Waals materials: magnetic graphene?
  There has been a huge increase of interests in two-dimensional van der Waals materials over the past ten years or so with the conspicuous absence of one particular class of materials: magnetic van der Waals systems. In this Viewpoint, we point it out and illustrate how we might be able to benefit from exploring these so-far neglected materials.
