Visualizing atomic structure and magnetism of 2D magnetic insulators via tunneling through graphene.

ABSTRACT: The discovery of two-dimensional (2D) magnetism combined with van der Waals (vdW) heterostructure engineering offers unprecedented opportunities for creating artificial magnetic structures with non-trivial magnetic textures. Further progress hinges on deep understanding of electronic and magnetic properties of 2D magnets at the atomic scale. Although local electronic properties can be probed by scanning tunneling microscopy/spectroscopy (STM/STS), its application to investigate 2D magnetic insulators remains elusive due to absence of a conducting path and their extreme air sensitivity. Here we demonstrate that few-layer CrI₃ (FL-CrI₃) covered by graphene can be characterized electronically and magnetically via STM by exploiting the transparency of graphene to tunnelin
