A new paradigm for voltage controlled topological antiferromagnetic spintronics is envisioned via proximity of a magnetoelectric antiferromagnet to a two-dimensional material. Using graphene/chromia as a model system, the authors predict the emergence of unconventional anomalous Hall effects that are electrically controlled by the N'eel vector as well as the appearance and transformation of different topological phases and the emergence of chiral edge states. The results advance the research field of topological phenomena and establish connection between the subfields of antiferromagnetism, magnetoelectricity, topology, spintronics, and valleytronics.
